Have used this from the get-go for all my gas rigs. Before that, used in all fleet gas rigs before retirement.
Always the best you can use. Hands down.
I only use amsoil in my truck and Harley, there's nothing better I think,been using it for years, absolutely no regrets excellent oil
Bottom Line
Yes, I would recommend this to a friend.

No more flat cams

I had a custom SBC race engine built and had issues with Cams going flat. First cam went flat after break-in and switching to OTC oil. Second cam went flat after 6000 miles on break-in oil and switching to Tier 1 Synthetic oil (which was guaranteed to work with my cam and lifters). Rebuilt entire engine for a 3rd time and started running Amsoil 10W-40 high zinc. 7 years later the engine is still running strong and makes same HP as the day it came off the dyno. I also run this oil in my truck, which pulls a racecar trailer on a weekly basis.
Bottom Line
Yes, I would recommend this to a friend.

Use this in my 26 year old F350. Still runs like new. It's my farm truck.

I’ve almost always used BMW recommended products for my car. As I know my motor is higher compression and extended service intervals, I’ve chosen 20W50 Amsoil. This product is awesome and has met and exceeded my high standards.
Bottom Line
Yes, I would recommend this to a friend.
