Engine oil Mobil or VALVOLINE

I personally use 5w50 valvoline fully synthetic racing oil for my r56 and change every 5000 km which is like around 3k miles and it's running good

The OE VW oil is Mobil 1 0W-20 ESP X2 with a zirconium marker and blue dye added for VW 508/509 requirements. The ESP X2 0W-20 is the only M1 product that meets the higher HTHS spec needed for VW 508/509. Its also API SP and has balanced chemistry for LSPI issues in other makes.

Mobil 1 5w-50 for the last few years.

I always used Mobil1 High Milage oil in my old truck before I sold it.

I run Mobil 1 in my bikes.

Mobil 1 Definitely. 0W20 in my 2023 Sonata Limited. 5W30 in my 2014 Sonata Limited.

I do my own oil changes. dexos is pretty much a quality certification standard and I use Mobil 1 Fully synthetic 0w-20. I did my first change at 1,5k then at 5k and will do one at 10k. I always replace the filter and I have a magnetic drain plug to collect shavings that may pass through the filter in case it ever is compromised.

Ive always used Mobil1 oil and filter and have 130k miles on my Veloster

For the money the best zinc content is valvoline vr1 CONVENTIONAL (not synthetic). It comes in a few flavors.

I was using Mobil 1 fully synth 5w40 on my old cab with no problem at all. good pressure at idle and at 2k. I used this oil in my new cab (same engine) and boom! No oil pressure at for the first 15 secs. Then it immediately jumped to 5 bars and finally settled down to 1 bat maybe less. However, I saw a dramatic increase in oil pressure even with the 5W40 mobil 1 when I switched to a 2L oil pump. Idle pressure was arround 2bars. Although I used it last summer and it worked just fine throught my vacations in Greece.
