Owner reviews for engine oil

I've always run conventional Castrol 20/50 in my Gti's (past and current Turbo) without issue.

Been using motul 8100 eco

I use Motul 300V. No complaints.

I have been using Mobil1 for a long time in all my cars. AFAIK it has performed will in independent testing for this car as well but the consensus is that the shell rotella is the best stuff you can get. i have also recently switched to 5w20 instead of 0w20 because i live in a climate where it never really gets cold and i wanted something a touch heavier for auto-x abuse. most people agree that we are talking about a very minor difference at best, but it does feel a touch smoother now.

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.

Mobil 1 15W50 [emoji106] Has plenty of ZDDP

Idemitsu zepro eco medalist advanced moly 0w-20. Basically the same thing as Mazda's oil.

The liquimoly additive, Oil Additiv p# 8352, did help me for a bit but now it's back to the usual oil guzzling. For my choice of engine oil I use 5W-40 Toptec 4100 liquimoly .... I think it reduced consumption somewhat over OEM castrol.

Everyone in the Oldsmobile community recommends Rotella

My machinist loves it

I use it in my 66
