Engine oil Shell or AMSOIL

5k with Rotella T6.

20 years driving modified STIs with zero issues.

I do 3k with Amsoil SS as well. Blackstone analyses of TBN show I could easily do 5,000k.

5000 miles with a quality full synthetic will serve you well for the life of your vehicle.

Maintenance, that’s what I’m focusing on rn so far ive done oil and coolant, went with amsoil and Nissan blue

Rotella T6 now comes in 10w-30 as well as a 5w-40 both are excellent choices.

I used AMSOIL signature, and do yearly oil changes.

I used Amsoil when I did mine. The squeeze bags they have make changing the fluid a lot easier and it's good oil.

I'll always use T6 because it's cheap, available, and damn good oil

I just purchased their OE formula @ $8.99 a quart...my 2012 Camry, 2ARFE has 212k miles and started burning oil around 150K. I was using Mobil 1 since I ownWe'll, and I noticed I was topping it off every other week...Now, I'm waiting for the oil and see if this will clean up the oil control rings, ring landings, etc. I'll report back.

Amsoil as an oil is trash. We used it for years and our reports were always tetering.
