Engine oil RED LINE or Lucas

I like the Lucas ones personally.

I use Redline, similar quality and price to Amsoil, without the MLM BS.

In my experience of trying many different oils, what I think are the best, as far as the engine running cool and smooth shifting are: 1. Redline 15w50

Red Line Racing Two Stroke is the best oil I've run. It leaves a good film and smells the nicest.

I stand by Redline 5w20. Not that I have bad “hemi tick” on my 5.7 but I swear the valvetrain is the quietest when I use that oil.

I personally use Red-Line products, and it's the absolute BEST products out there. Their 2 Stroke racing no smoke oil is OUTSTANDING and 2nd to none.

Redline and royal purple filter for my 17 ram sport 5.7. 60kish on it now.

I always used redline 5w50 on my S65 runs very well and redline has a great reputation of quality oil especially for its high performance cars. Takes less time to warm up too in low temperature climates.

That looks like you dropped a valve. Yes Lucy’s oil will help. It will lubricate the chamber so you can take out all the pieces.

I installed an oil cooler on my buddy's 370z and he dumped in oil and a full bottle of this and I just scratched my head
