Engine oil RED LINE or Eneos

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

I use Eneos on my 2013 WRX since day one.

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

I have used Eneos 5w30 in it since I bought it. This is a group 5 oil and I believe that it saved my ass. Last summer going to work my car blew the top radiator hose off. I was about 3 miles from work and so I decided to just drive it. The temp gauge was pegged all the way. Come to find out my radiator inlet broke since it was plastic. I was able to get the hose back on after work and filled it up with coolant. Replaced the radiator with an aluminum CSF two row and knock on wood everything has been good since. Not losing water or oil and no smoke coming out the tailpipe or anything.

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’ve used Shaffer’s and now ENEOS and T6 when it was the in thing and I can’t really tell a huge difference.

So when i changed the car to 10w40 redline I noticed that the car began to knock around 3-4k which it didn't do before and now it seems to slowly get worse.
