Also, I know some people debate on oil weights whether to run a straight weight or a multi-weight as well as the debate on conventional vs synthetic.

I dont know a lot on the subject but here is what I do know and I'm sure many of you know this as well.

99% of engines of course will benefit from a multi-weight oil. This is simply because we need a a thin oil to start the engine when cold but for protection we need something slightly thicker once warmed up. This is unless of course you're running a pure race engine such as an NHRA Pro Stocker running 0 weight.

The fact is, in a multi-weight oil there are many more polymers. As the engine and oil temperature warms these polymers begin to unwind which then causes them to take up more room while not allowing the oil to get thinner.


As for synthetic vs conventional.

When it comes to a performance aspect the synthetic will be a better insurance policy. It gives a greater load area causing the molecules to be harder the break apart. This also helps to cause less friction.

Also, if you dont want to run 100% synthetic it has been said by many in the racing world that.... SUPPOSEDLY 1 quart of synthetic into 5 quarts of conventional is 80% as good as running a full synthetic. That is just what is said



I understand many of you already knew all of this but in case theres a few people who dont, hopefully we can help get them going in the correct direction
