We use it in the race engines with every oil change. On street cars, every other change.
It contains EP and anti-wear additives not found in most all current motor oils. There is no downside to using it except cost. If so, use half a bottle with an oil change.
Having never wiped an aftermarket cam, except one using synthetic oil, I am afraid NOT to use it!
Miight as well get used to using it from now on, with the recent changes to what's allowed to be added to oils. There some threads convering this.
Especially for flat tappet cammed motors, IMO.
Synthetic oils and Conventional oils are compatible across the board. It is one of the standars of API. (American Petroleum Institute). It is not ideal to Mix them but it will not cause any problems. Synthetic blend is a conventional oil with the synthetic additive package inserted into the mix. EOS is a variation of friction modifiers, ZDP and other types of additives. It was said once that the EOS can replace depleted additives in your engine oil when it is close to being due for a change. It also helps keep the lifters free and moving and quiet.
Should you use EOS in your car? You bet your a$$ you should!
Yes it is ok to use it with Synthetic or Conventional oils.
I bought one today.It says do not use this product as a oil supplement.Use this product to lube bearings,cam,lifters,pistons,rings during engine assembly.I think
I`ll use 4 oz. on my oil change
There was a write up in the GSXTRA newsletter recently showing the EOS being used as a motor oil supplement and why it's beneficial etc.. It is worth adding it.
