Engine oil Castrol or VALVOLINE

Castrol 5w40 Euro spec, my car runs better on that than 5w30

I use just regular old Castrol Edge full synthetic 0W-40 in my 2012 Jetta year round, currently has 156k miles on it (251km).

I used both wrong spec oil and wrong weight oil on my 06 Rabbit 2.5 for about four years. I was an idiot. However, nothing ever happened. I'm at 223,000 miles and the cams look brand new, engine runs smoothly.

Castrol works fine.

Dont use the cheap stuff. Liqui moly or Castrol!

This is what I use… with a Fram synthetic oil filter.

I have been using 5w-20 for more than 3 years on my Accord 2004 (330K) and 2003 (230K). I have no issues with both and the engines runs the same as before using other oils like Castrol Magnatec.

Valvoline MaxLife 10W40. Made specifically for older engines with high mileage.

But as a fellow 7.5 owner i switched to 15w-40 when going stage 1 because where i live temps regularly even in winter are around 98-105 degrees and i was finding i had to top off the oil every 1,200 miles, since the switch to the thicker oil ive done 2,500 and the level is exactly the same

Smedia had a video about this and he had more wear with less miles using Motul over Castrol in a Blackstone report. So for me just the convenience and price of Castrol edge I'd pick it over Motul. Knowing it had less wear wear was the nail in the coffin of buying overpriced and often several year old Motul.

Castrol. I've just always used it. A bit of advice though, i'd recommend staying away from Pennzoil, I had to clean an engine out after using it. Nasty, waxy stuff.
