Engine oil Mobil or VALVOLINE

I switched to valvoline restore and protect on my 06 is250 and it’s working great. The valves are a lot quieter compared to the previous oil I was using which was Kirkland synthetic.

Mobil 1 is a fantastic oil.

I have 265k on my 2002 Weekender purchased new. Run Mobil-1 0W-40. No problems with engine but transmission needs TLC.

When I switched from Kirkland I noticed no condensation under the oil cap vs having a milky consistency under the cap. I think the hybrid oil deals with moisture better in these hybrid engines.

I used Mobil1 for a decade and around 50k with no issues.

Quaker State oil is recommended in the Hyundai manual but you can absolutely use other brand too , i have used Mobil 1 / Vavoline / Castrol and Pezoil the end i picked Valvoline high mileage Synthetic oil the best of all all other brand the oil burn brown quickly

I’m at 80k miles and only used mobil 1 ESP x2 0w-20, don’t wanna mess around with any other viscosity, I’m not smarter than VW engineers ????‍♂️

Mobil 1 is my go-to... mostly because the level gauge on the side of the container is easier to read than any other brand. I've been using it in my 2018 since new and have never had an issue. Odometer is currently at 260,000.

My wife drove her 2008 Passat 2 miles per day for six years. As you can imagine, during these very short drives in winter, the oil became diluted - this was born from sever UOAs. So, I changed the oil every 1,500 miles and the oil and filter every 3,000 miles. Over-kill perhaps but based upon my personal expectations, worth the time and money. We used Mobil 1 0W40....which sheared to a 0W30 fairly quickly and stabilized.

Fellas, Don't bother running Mobil1 for extended period of time. I have done 2 consecutive oil tests on Mobil1 0W-40. One with 6200 miles and the other was at 4700 miles. Used OEM filters in both cases. Results: With the 6200 mile drain interval, the iron and the lead levels were up there through the roof! With the 4700 mile drain interval, the iron was within average and the lead was couple of points above the average.
