Engine oil Shell or MOTUL

I always buy engine oil from Lotus (Tesco). Shell Helix especially on sale.

Order some Motul 5100 online. Good price for great oil.

I really like Motul. Used to use 300v it got expensive changing it so much. 7100 has a longer oil change interval and for all intents and purposes is just as good as 300v for street use

Motul 7100 seems to do the trick. Great for city riding and long trips, moderately high revs in the hills, etc.

Motul 5w40 X-cess, suggested by multiple reputable indies.

I use Motul classic 20W-50 in all of mine, or some generic 20W-50 oil if I can't find it. If I'm not incorrect the classic has some additives to help with not seeping out of the engine but other than that won't do anything special.

I see a lot of people recommending lighter oils but living in a warm climate this is what works for me.

Motul Xclean EFE 5w30, Xclean gen2 5w40

That said, I use Motul 0W20 in the winter and 5W30 in the summer.

I send an oil sample to Blackstone Labs every single time I change the oil or the dealer changes the oil. As part of that analysis, I pay the few extra bucks for a TBN calculation. On my SQ5 and S3, after running a fill for 10k to 12k, those TBN values always come back greater than 1.0 indicating that there’s still enough remaining additives to continue running that fill for even more miles still.

The same oil goes into all GDI engines at my dealer, which is Shell Helix Ultra SP 0W-20. This is a super expensive, latest spec oil. Oil changes with this oil are done at 9320 miles if turbocharged and 18 640 miles if naturally aspirated.
