Will thicker oil damage my engine?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.
What’s a good racing oil?
What is the best oil to use in racing engines? Professional racers across North America recognize AMSOIL products as the best and most effective available. The number of championships and checkered flags claimed by AMSOIL sponsored racers is testament to the extraordinary performance AMSOIL products provide.
Is 5W-50 thick oil?
The 5w50 oil has a higher viscosity than 5w40, which means it’s thicker and can perform better under high-load. However, this also means that it’s more resistant to shear, meaning that the engine oil won’t thin out as fast as a lighter weight oil at high temperatures or in higher load situations.
What is the difference between 5W-50 and 5w40?
The main difference between 5w40 and 5w50 is the high-temperature index, making 50w40 less stable at high temperatures and loads and 5w50 more stable. 5W40 oils have a somewhat lower viscosity and are generally synthetic lubricants, but 5W50 oils have a higher viscosity than 5W40 oils.
What motor oil has a high zinc content?
For best protection, engine builders and gearheads typically use high-zinc and high-phosphorus motor oil to offer extra protection for flat-tappet cams, lifters and other components during break-in. AMSOIL Break-In Oil, for example, contains 2,200 ppm zinc and 2,000 ppm phosphorus.
Does Valvoline VR1 have ZDDP?
Yes, I understand Valvoline VR1 Racing Oil does have enough ZDDP in it, and I agree with your findings.
What is the difference between 5W-50 and 20w50?
The first number refers to its viscosity, or resistance to flow, when cold (e.g. 5W). Think of the “W” as standing for “winter.” The lower the number, the faster the oil will flow when cold, meaning a 5W-50 oil will flow faster at startup than a 20W-50 oil.
What is the difference between 5W-40 and 5W-50 oil?
Is it better to use thicker oil in high mileage engine?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.
Why are racing oils thicker?
Racing Oil Needs to Be Thicker
Racing oil tends to have a high viscosity because it enables them to provide the right coverage even in the increasing heat faced during a race. For example, AMSOIL´s DOMINATOR® SAE 60 Racing Oil has the right viscosity to keep the engine safe when high temperatures are reached.
Is Thicker oil better for racing?
Higher Viscosity Lubricants are Better for Heat Resistance
Racing oil needs to be thicker so that when confronted with high heat it will remain consistent enough to coat the engine parts properly. Regular car engines do not face the intense heat conditions that race engines do and so they do not need a high viscosity.
What oil do Nascar cars use?
Mobil 1™
Mobil 1™ is the Official Motor Oil of NASCAR® ExxonMobil and NASCAR have a long-standing partnership, with the Mobil 1™ brand serving as the Official Motor Oil of NASCAR since 2003.
What is the difference between 5W-50 and 5W40?
Can I mix 5W40 and 5W-50?
Can 5W40 and 5W50 be mixed? It is possible to mix engine oils, but in rare cases and under certain conditions, using the oil of the same brand and without overusing such mixtures. It should be understood that the viscosity of the oil will drop or rise, depending on the amount of added oil.
Is 5w-50 thick oil?
Which engine oil is better 5w30 or 5w40?
5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.
Can you put too much zinc in oil?
If you have too much ZDDP, you start to see corrosive wear and cause another problem. Adding an excess causes the oil to become acidic, and before you know, you’re wearing cams, bearings and bushings because of too much ZDDP.
When did they stop putting zinc in motor oil?
1994
As most enthusiasts should be aware, new car manufacturers reduced the level of zinc and phosphorous (also called zinc dithiophosphate, or ZDDP) in engine oil beginning in 1994. This change demanded a new oil designation from the American Petroleum Institute (API), which has now evolved to the current SN designation.
How much ZDDP is enough?
ZDDP is most effective if the concentration is between 0.18 and 0.2 % by weight. Tests have shown that concentrations above this amount, up to as much as several percent, have no effect except to prolong additive life.
Can thick oil damage engine?
It’s best to use the oil viscosity recommended in the owner’s manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.
What is the thickest motor oil you can get?
Importance of a Viscosity Scale
In order to have a standard way to measure the viscosity of engine oil, the Society of Automotive Engineers (SAE) developed a viscosity scale. The scale ranges from 0W, which is the thinnest type of oil, to a rating of 60, which is the thickest oil.
