Used in a buddies 90’s GTR. He said they lose some oil pressure once they get warmed up so he wanted to try the 40WT. So far he says it’s better and quieted the engine down

Outstanding product

Been using Amsoil products in both my truck and small SUV now for just over a year, so I’m still new to the game to give solid information. What I have seen over the year is a quieter engine in my 130k + SUV and a slight savings in fuel in my truck with proper maintenance and oil change intervals. It’s a little pricey over other brands but the quality and noticeable difference justifies the price IMO, plus if you opt for a membership you save on each purchase.
Amazing product…. 5 stars!
Bottom Line
Yes, I would recommend this to a friend.

I started using Aimsoil 40 years ago in my chainsaw. I was so impressed that that is all I use in my truck now.
