Engine oil Shell or PETRONAS

RotellaT and Wix. Since my first turbo in 2007.

I used Rotella T6 in my old Subaru. It solved the oil consumption issue that boxer engine had. Seems like most people on NASIOC run T6. So if your car burns oil, it's worth a shot.

I've used it in my Z06, Suburban, my wife's Ford Edge Ecoboost and my old Gixxer and R6.

It's a good oil and cost effective.

It's synthetic, has decent additives and won't hurt anything in any of your vehicles.

Rotella T6 is a great oil for these cars, and it's what I use.

If I feel like spending money I\u2019ll buy Redline or Motul, they\u2019re Group 5. If I wanna be cheap and still want really good oil I\u2019ll buy Rotella T6.

Rotella T5 15W40 seems to be on sale somewhere at all times for an absurdly low price + a filter. Ive been using that in my JH block with G60 topside.

i use shell rotella 15w40 WHITE bottle.

Everyone in the Oldsmobile community recommends Rotella

My machinist loves it

I use it in my 66

I used to use Castrol GTX 20W50 oil with Bardahl B2 additive, but after some discussion on the Bob is the oil guy forum, I decided to try a lighter oil: Shell Rotella 15W40 without any additive. It feels a bit easier to start and runs great (but it did ran great before). However, the oil pressure is certainly lower

I've used Shell Helix Ultra 5w-40 and 0w-40 in my AQY. (we have cold winters here) Both seem to work well, no additional lifter noises, normal mileage. Engine sounded good even just before this years oil change.
