Engine oil Mobil or Shell

I use the Mobil 1 Racing 4T 10W-40 which is synthetic *and* meets JASO, just because it is always available at the nearby Walmart.

I use Rotella T4 on my 2.5L and have been for years because high ZDDP helps with the valve tapping I have going on. It has actually gotten quieter over time and feel the engine is running smoother than ever.

I use M1 5-30 because I've ran it in well over a dozen cars and beat on all of them without issue, and it's only $28 for a gallon jug at walmart. I also run liqui moly ceratec to silence the typewriter tick it developed around 35k.

I’m using the 0w16 from Renault that probably is a Shell RN17, I have about 25.000km now and I will do the third change on the beginning of next year… but in the sandero that I also own I changed to 5w30 (from 0w20) both RN17 and the engine feels way softer and silent…

I recall mobil1 going red being normal.

gamit ko yung city scooter sa adv ko. laki ng nabawas sa vibration nakaka 2500km palang ako with this.

Shell, better oil and last longer. I use petronas cepat habiss woo minyak walhal jalan sama je balik kerja.

Mobil 1 ESPx2 is the right choice here. The regular 0W-20 does not carry the VW 508 00 approval, whereas the ESP one does. It’s a great oil to use!

Rotella T6 5w40 in my EJ255, its helped a tad with the leaking until I can get everything apart to seal it all up again.

I learned mobil 1 is the absolute worst oil to use in Subaru engines, especially ej257. Simply because it is good oil but because of the poor oil cooling the detergents burn in the engines causing premature wear.
