Engine oil MOTUL or Motorcraft

Here is what IAG recommends

FA2ODIT (91 or 930ct) - Motul 5w30 8100 X-clean EFE, change oil every 2500-3000 miles

Motul 5w-40 8100 X-clean Gen2 may be used in climates where the average ambient temperature is above 80° fahrenheit. It is important to note that the oil used must carry the GM dexos 2 rating.

Motul. Always. Held up over 500hp for 2 years zero issues on unopened stock block plus its what almost all tuners recommend.

Motul 8100X-Clean for me, no problems!

I’ve been runnin Motul 7100 full syntetic for the last 15.000 km’s (9300 miles) never had an issue once.

I ran motorcraft for like 70,000km's and switched to amsoil 5w50 after that.

The red Motul is amazing stuff!

Motul 4T 7100 10w40.

Engine works like a charm, gearbox changes gears effortlessly and the oil smells nice as a bonus.

I’m in MD and use Motul 5w30 X-clean EFE

I started using motul 10w40 after my apache rtr 180 crossed 50k kms. It gave the old engine required smoothness and the engine feels stress free.

I just put in Motul 8100 instead of whatever the dealer was using. Haven't really noticed a difference except it's occasionally burning a bit, but I can't say for sure that it's just because of the oil.
