Engine oil Shell or MOTUL

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.

Been using motul 8100 eco

I use Motul 300V. No complaints.

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

My next step is to switch the oil to Motul 8100 X-Cess (this is what I used in the past before moving to Ottawa).
