The viscosity rating of a motor oil is determined in a laboratory by a Society of Automotive Engineers (SAE) test procedure. The viscosity of the oil is measured and given a number,which some people also refer to as the”weight”(thickness) of the oil. The lower the viscosity rating or weight,the thinner the higher the viscosity rating,the thicker the oil.
Viscosity ratings for commonly used motor oils typically range from 0 up to 50. A”W”after the number stands for”Winter”grade oil,and represents the oil’s viscosity at zero degrees F.
Low viscosity motor oils that pour easily at low temperatures typically have a”5W”or”10W”rating launch x431 iv. There are also 15W and 20W grade motor oils.
Higher viscosity motor oils that are thicker and better suited for high temperature operation typically have an SAE 30,40 or even 50 grade rating.

SYNTHETIC MOTOR OILS
Synthetic oils are oils that are refined to a much higher degree than ordinary oils. Synthetic oils are premium oils that generally have greater viscosity stability,lower pour points and can withstand higher operating temperatures. Synthetic oils improve cold starting,reduce friction,reduce oil consumption and improve fuel economy and performance — but they typically cost about three times as much as regular motor oil.
Some suppliers of synthetic motor oils say the higher cost of their premium quality synthetic oil can be offset by extending oil change intervals. But this would depend on the operating conditions,age and condition of the engine.
Synthetic oils are a good upgrade for most engines,but are not recommended for breaking-in newly rebuilt engines.
SYNTHETIC BLENDS & SPECIALTY MOTOR OILS
For motorists who want the benefits of a synthetic oil in a less expensive product,there are”synthetic blends”that mix 20 to 25% synthetic oil with conventional oil. Blends cost about a dollar a quart more than ordinary oil,and provide many (but not all) of the benefits of a full synthetic.
There are also oils that have special additive packages for specific applications such as large,heavy Sport Utility Vehicles (SUVs),turbocharged engines (extra anti-oxidants) and high mileage engines (extra viscosity improvers and anti-wear additives).
OIL CHANGE TIPS
* Drain the oil while it is hot. Contaminants will be in suspension and drain more easily from the engine.
* Always replace the filter when changing the oil.
* Wipe some oil on the filter gasket so the seal won’t stick or tear.
* Hand tighten the filter about 1/2 to 3/4 of a turn after the gasket makes contact. Over-tightening may damage the threads or gasket,and make the filter difficult to remove the next time the oil is changed. Under-tightening may allow the filter to work loose and leak.
* If the oil is badly contaminated or sludged,the crankcase should be cleaned and flushed before the engine is refilled with oil.
* Always check the oil level after refilling the crankcase. Start the engine,then shut it off and check the oil level after several minutes. It should be at the full mark on the dipstick. Most engine hold about four or five quarts of oil,plus half a pint to almost a quart for the filter (depending on the size of the filter). Overfilling can cause oil foaming and leaks. Under-filling may cause a loss of oil pressure and engine damage!
* Dispose of your old used oil properly. Save it in a container and take it to an auto parts store or other facility that recycles oil. Do NOT dump it on the ground,down a storm sewer or anyplace else where it would contaminate ground water.

How Does a New Engine on a Used Car Affect Price?
A brand new engine can definitely affect the price of a used vehicle.
Selling a used car can be difficult under any circumstances,but a used car equipped with a new engine can definitely improve the selling process and have a net positive effect on the price.
Enhanced Performance
A brand new,factory-made engine in a used car is definitely a selling point. A used car with a new engine can command a higher price than the same car with the original engine. This is obviously because of the fact that the new engine will have none of the wear and tear of the original engine and should,therefore,enhance the vehicle’s overall performance.
Explaining Used Car Price
Organizations such as Edmunds and Kelley Blue Book use depreciation models to determine the current value of a used vehicle based on the original manufacturer’s suggested retail price and current operating condition launch creader crp129. So,a new engine in a used car that was once in poor condition may elevate the condition to good or very good and thereby increase the selling price that could be offered.
Warning
Just because the engine is new does not necessarily mean that the vehicle will sell for a price any higher than the Kelley Blue Book value. This is because those prices assume that the vehicle is already in good working condition,with an engine that is functioning well. The addition of a new engine does not make the entire car”new”and it cannot be sold as such launch x431.

The What,Why and How of Wheel Balancing
By Sean Phillips

Wheel balancing,also known as tire balancing,is the process of equalizing the weight of the combined tire and wheel assembly so that it spins smoothly at high speed. Balancing involves putting the wheel/tire assembly on a balancer,which centers the wheel and spins it to determine where the weights should go.
In essence,wheels and tires are never exactly the same weight all around. The wheel’s valve stem hole will usually subtract a small amount of weight from that side of the wheel. Tires will also have slight weight imbalances,whether from a joining point of the cap plies or a slight deviation from perfectly round,because that kind of perfection is impossible to achieve. At high speeds,a tiny imbalance in weight can easily become a large imbalance in centrifugal force,causing the wheel/tire assembly to spin with a kind of”galumphing”motion. This usually translates into a vibration in the car as well as some very irregular and damaging wear on the tires.
Traditional Spin Balancing
To balance a wheel and tire assembly,we put it on a balancing machine. There are several ways to manually balance tires,but they frankly do not compare to machine-balancing in terms of either ease or precision. The wheel goes onto the balancer’s spindle through the center bore,and a metal cone is inserted to ensure the wheel is perfectly centered. The machine spins the assembly at very high speed to determine the heaviest point,and signals the operator where and how many weights to place on the opposite side to compensate.
The most important things to know about balancing are:
* Balancing Is Necessary: A weight imbalance in every wheel/tire assembly is pretty much inevitable. Only once in a very blue moon do we see an assembly come out naturally,perfectly balanced,(I always joke that they really should put a flashing light and a bell on the machine for when it happens) and discovering a balance is just as much a function of the machine as discovering an imbalance.
* Balance Changes Over Time: As the tire wears,the balance will slowly and dynamically change over time. Most good tire places will want to rebalance when tires are rotated,or when swapping in winter/summer tires for a second season,for example. Rebalancing at least once over the life of the tires will almost certainly extend said lifetime.
* Balancing Only Fixes Balance: Balancing will not prevent vibrations from a bent wheel,out of round tire or irregular wear. Balancing weights can’t compensate for a problem that is actually physical in nature,they can only compensate for weight differences. As well,one of the first mathematical assumptions the balancer’s silicon brain makes is that the wheel and tire are both round to within a certain maximum deviation,so if a wheel is substantially bent,for example,the balancer will probably end up getting the weight placement wrong in the first place.
Road Force Balancing
Because there are those other reasons than just balance for vibrations and strange tire wear,eventually the”Road Force”balancer was born. This style of balancer,in addition to performing a traditional spin balance,also measures both the wheel and tire to determine if there are conditions that would tend to cause a vibration on the road launch x431 iv. Generally,most balancers do this by pressing a large roller against the tire as it spins slowly,reading out tire pressure and radial runout. (. deviation from perfect roundness.) This can detect conditions like belt separations,where the steel belt has been bent and is delaminating from the surrounding layers of rubber,as well as match mounting issues.
Generally,both wheels and tires will have high and low spots in terms of their runout,because as I noted,perfection is impossible. If you can imagine pulling one point of a connected circle (such as the edge of a wheel) just slightly outwards,you can see that some other point of that circle must move inwards to maintain the connection,creating an egg shape. These are high and low spots for radial runout. If you can further imagine putting on a tire such that the high spots for both the wheel and tire match up together,then those high and low spots will add together rather than canceling each other out. If balanced on a traditional balancer,this assembly will not only require more weight to balance,but will still probably cause a vibration.
The solution is to measure both the wheel and tire,and then move the tire around on the wheel until the high spot of the tire matches the low spot of the wheel. This process is usually called”match mounting.”Most tires today have small dots on the sidewall to indicate the point on the tire that should match to the valve stem to get a decent match mount,Road force balancers do a much more precise job of this by measuring both the wheel and tire with rollers and then directing the operator to mark the points to be matched. The resulting assembly requires less weight to balance and spins straighter.
Bang-on vs Adhesive Weights
In the beginning,there were bang-on weights,lead weights of various denominations with a soft lead flange that were knocked onto the edge of the wheel with a plastic hammer. And while wheels were steel,behold,these weights were very good. But yea verily did steel wheels beget alloy wheels,and verily did these weights break the clearcoat on expensive painted aluminum wheels when smacked onto the cosmetic face. And verily did they hold water nicely up against that break in the clearcoat,allowing the demon Corrosion to have it’s foul way with the unprotected aluminum surface beneath. And yea,did wheel owners everywhere fill the air with various four-letter lamentations.
But then,as if in answer to our prayers came Tape-A-Weights. Strips of flat adhesive-backed lead squares,each square weighing one-quarter of an ounce,the weights can be cut to size with clippers and stuck to the inside of the barrel behind the spokes. And there was much rejoicing… The adhesive is quite strong,but wise tire techs will still clean the surface where the weights will go to make it free of brake dust and grease if at all possible. This will prevent the weights from falling off. If there is any question of the adhesive holding Creader VI,a strip of duct tape to cover the weights will hold through just about anything. Racing techs use duct tape to hold weights on wheels under heat conditions that would melt the weights’ adhesive.
So that,boys and girls,is why using bang-on weights on the face of an aluminum alloy wheel is a terrible sin. Always ask for adhesive weights when you have your alloy wheels balanced. Be suspicious of any tire place that does not use adhesive weights. Many places will use bang-on weights on the inside flange of the wheel and adhesive weights for the outboard side. (Bang-on weights are generally less expensive.) This is usually perfectly acceptable unless you have chrome wheels,where any break in the chrome can begin the flaking process and can eventually be fatal.

As the saying car need 70% maintenance 30% repair, maintenance of the surface paint is also for the same reason, in fact, regardless of the finish waxing, sealing glaze, or automobile coatings, paint them just to add a layer of protection, these what is also necessary, but the important thing is the follow-up of the car wash, since 90% of paint scratches car wash are all produced below teach you how to keep a good car paint.

First, when the car wash is best not to use water cannons to wash it, because some of the dirt once the paint surface is flush gun cannot afford, it is best to use soft water soaked first look, the soft water soaked to soften the dirt on the, and then use high-pressure water to flush out flush directly, especially in some mud and more vehicles have to pay attention, the soil is sand the paint harm.

Second crp129, when you do choose a neutral car wash car wash liquid , alkaline washing liquid to paint too much of a certain erosion , neutral paint washing liquid can maintain smoothness and brightness , the paint will not accelerate the oxidation when the car wash would be best if the conditions inside the wheel hub can also swipe , powder brakes attached above a long time without cleaning , then the future will be difficult to dispose of , but once the oxide powder brake wheels will turn yellow , the impact of the vehicle beautiful.

Third launch x431 pro, when the car wash car wash towel is a very important tool, Cache clean towel or not, relates to the extent of damage to the paint, so scrub cars to choose clean and fluffy towels, best paint, interior, and wheels are separated with a towel.

Fourth, paint the surface maintenance waxing, sealing glaze, coating preferably inorganic, do not like oil and fluorine, oil paint coating after by sun exposure, will be a series of chemical occurrence reaction, oil and fluorine class has been doing for a long time have the effect, paint will be very bright, but once stopped, these substances will accelerate paint oxidation, so there is no dark gloss finish.

Fifth, do not wash the vehicle too frequently, mostly scratches vehicle cache wipes out, and the water will have a certain impact on the finish.

Sixth, try to mop few cars and computers washing machine, belonging to mop paint dry friction will produce beautiful and more scratch impact of vehicles. Long-haired computer washing machine which will contain a lot of sand, can damage the paint surface.

Seven , bird droppings and gums, when air conditioning water erosion paint to timely treatment, these things are a big harm the paint , but be aware that these things encounter with a wet towel to get the best deal Sheung Shui to go , or will damage the finish.

Does Engine Coolant Go Bad?
Yes,engine coolant does deteriorate over time,but unless something unusual occurs,you probably won’t need to change the coolant in most late-model vehicles until 100,000 miles. Older vehicles probably require more frequent coolant replacement,so check your owner’s manual to be manufacturers now use extended-life coolant with a recommended change interval of 100,000 miles. That varies based on maintenance schedules for each manufacturer and individual models. Some Subarus,for example,call for coolant replacement after 13 years or 132,500 miles. Many Ford engines say to replace it after the first 100,000 miles and every 50,000 miles thereafter,though heavy-duty applications (such as frequent towing) should have it done more matter what the maintenance schedule is for your vehicle Launch X431 Solo,after a few years of ownership it is a good idea to have the coolant checked by a professional periodically for acid buildup,rust and other contaminants,and for its resistance to freezing and boiling crp123. If you have added water (particularly tap water) to top off the cooling system,you may have introduced contaminants or diluted the antifreeze/water mix (generally 50/50) and altered the freezing and boiling your engine is running hotter than normal,deteriorated coolant could be a possible cause. Most manufacturers and service shops recommend flushing the cooling system at the same time the coolant is replaced to get rid of deposits that accumulated over the specify certain types of antifreeze,and some may be red,others pink or green,but don’t go to an auto parts store looking for the right color. You need to ask for the right type of antifreeze for your vehicle,whether you’re adding some yourself or having it replaced by a pro.
