Engine oil Shell or MOTUL

I've always used Liqui Moly 5W-40 Leichtlauf, but yesterday I decided to put Motul X-Cess Gen2 5W-40...same quality? less money? I'll test that after 8k km and compare it to liqui

T6 Rotella 5w-40 when I run test pipes on tune, the heavy weight is great for keeping oil temps down and the zinc is awesome as a friction inhibitor but is terrible for cats so when I’m going to pass emissions I run Kirkland 5w-30 full synth on stock cats.

I prefer motul as I’ve used both and motul gives me less oil consumption from burning/passing through rings on my mk3 TT.

I love my Motul Xcess 5W-40, just becoming harder and harder to find.

I pay about that. Quality oil and filters cost money. Many shops price oil changes as a loss leader. Euro oil changes are not sold this way, you pay the true price of the service (roughly $80 in supplies, half an hour of labor). I pay ~$160, But you get quality oil in return.

I made myself the services, and used Motul 7100 10w50, I can feel the gearbox it's smoother.

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.

Shell Advance Ultra for scooters. Mahal pero kalidad. Change every 2k - 2.5k. You can extend a bit more observe mo lang performance ng makina every interval.

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

Motul 5w40 every 3500ish miles
