Engine oil AMSOIL or ROWE

I change oil once per year, using a high-quality synthetic that meets specification 504. I generally drive 8 to 9 thousand miles per year. The maker of the oil I use (Amsoil) says to follow the car maker's change interval.

For me at least, I use a 5w-30 Amsoil on my TLX Type S.

Not really . My tuner (jackal motorsports) recommends Rowe RS synthetic oil . Currently using LM molygen , it's ok but apparentlyThe RS is the best stuff

You can use Amsoil just fine, one of the best oils on the market.

I\u2019ve been running Amsoil signature 0w-20 in my FL5 for about 5k miles now. No track driving, just a mixture of city/highway. Some spirited pulls and rowing through the gears but mostly normal driving. Car is stock aside from PRL intake and custom tune. Had Blackstone do an oil analysis after the first 3k miles and all was well and below the average for all wear metals. I\u2019m in Florida so pretty hot climate overall. Very happy with the oil and will continue to use it at that viscosity

Amsoil 5w-40 full saps

Im using amsoil. Change oil interval every 5k. Pag gipit, 6k kms.

I've been using Amsoil for mine since bought new

I never ran Pennzoil, but I have Amsoil. Amsoil is good, but too expensive.

I've used amsoil 5w40 European formula ir worked great for when it was a street car, switched to royal purple 5w-40 due to a recommendation and immediately regretted it, tons of blow by I didn't have before. Dumped the royal purple CRAP as soon as possible, just a few miles on it.
