Engine oil Mobil or MOTUL

I’ve used Mobile 1 full synthetic for years, most manufacturers warranty it.

i have a 5qt of Mobil 1 sitting around in case i ever need to take it in for warranty work.

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.

I run Mobil 1 15w50 in Colorado in my 1.8 8v 85 GTi. For camshaft insurance I add a zinc additive at oil change time.

I use Mobil 1 15W50 zddp conent is higher than regular oil.

Used Mobil 1 in all my Toyotas for the last 20 years. My dad's Scion xB is close to 400k miles running strong.

Stick with 5W50. Brand doesn’t matter as long as it’s a quality supplier. I used Mobil 1 in the beginning

Always used M1 on my 30 year old Celica/camry. They both run flawlessly. Done over 30 changes on the Celica (160k miles)

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.

I ran M-1 15w50 for 10k miles or so, and my car ran 10 degrees hotter on average than with any other oil I've used. Throttle response also felt sluggish.
