Sure! there is nothing wrong with them just try to make sure you dont overfill your engines oil limit. As heat and gases form during combustion it causes the gradual depletion of the oils high temperature viscosity index (VI). This is due to a combination of "shearing" of the VI improver and fuel dilution of the crankcase. This "shearing" can be described as the destruction of the VI improver's physical structure such that it is no longer capable of effectively thickening the oil. It is not uncommon for a quality motor oil to lose one whole viscosity grade during a normal drain interval, a 10W-40 might be reduced to a 10W-30 after a few thousand miles. A quality additive will help replace or prevent the loss of important chemicals to give your oil a vast improvement. Frequent new oil and filters are the best protection.
Oil additives are something I do not recommend you use. The purpose of these additives is to rid you of your money while doing nothing for your engine.
You don't. Add not additives to your oil. If additives worked the manufactures would add them to the oil and recommend you also do so.
Don't. Add no oil additives to your engine. If oil additives were really that good, the oil companys would put them in their own oil.
mobile 1 and never use and other additives
Airplane oil! Really! There are two kinds, depending on what kind of engine you have in your plane. Piston engine planes use "aviation oil," which has additives in it to withstand being in an engine that's running at full throttle all the time. Jets, turboprops and turboshafts use turbine oil, whose additives are made to withstand extreme heat.
No, they do not release friction they reduce it. Some friction will always remain in the common modern internal combustion automotive engine. Engine oil additives actually reduce the amount of friction that can be very intense and harmful to a engine, especially when starting from cold. Chemical polymers and agents that make up the engine oil additives are designed and engineered to add a level of extra protection to the standard engine oil. However, a good name brand engine oil, installed into your vehicle with proper weight and viscosity and proper oil manufacturer recommended additives -which are already in motor oil from the manufacturer - is all that is needed. No other additives should be used unless the automobile manufacturer has suggested it's use.
That is what you should use. I recommend you use synthetic oil in this air cooled engine.
No, I would not recommend using synthetic in an engine this old. Use a good 10w40 conventional oil.
If you do not want to use Polaris trans oil ,they recommend 30 w engine oil
SAE 10w30. I recommend you use synthetic oil in any air cooled engine.
As long as the engine is ok you can use: 10W30 10W40 I recommend using Vavoline.
Depends on which engine but most use SAE 10w30 weight. I recommend you use 100% synthetic oil in an air cooled engine.
