Engine oil Mobil or Shell

Our engines were originally designed for 5W30, so that's what I use. Namely Mobil 1 High Mileage.

I have a 22 Tiguan and did the first oil change myself around 5K miles. This is what I ended up using. I found it locally so that was a plus, Mobil 1™ ESP X2 0W-20 .

My 1.8t is currently filled with Rotella T6 and I swear its eating less oil now (or maybe I'm getting better with my heavy foot)

Been using Mobil 1 for over 20 years. Never had any issues.

Mobil1. I use 10w30 in the Texas summer heat and 5w30 in the winter. 2006 c280 with 185k

Mobil 1 extended oil. Full synthetic 5W30 changed every 12,000km. Mine burns about 1 litre (pint) per every 1,500-2,000km. So I top up a few times between full on oil changes

I use Mobil 1 full synthetic because I also use it for my car, and if you send you oil off to a lab after you change it, even at 3000 miles the oil was still in great shape.

Ran Mobil 1 Advanced Fuel Economy for a while and it was fine, but lately I've switched over to the Toyota branded. It's more expensive, but I only change my oil once a year because I don't drive it much, and I like the higher molybdenum content in the Toyota stuff.

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

I just did the chains + headgasket and a bunch of other misc stuff on my Corrado earlier this year. My guides were worn pretty bad and it only had 120k on the clock.
