Engine oil Castrol or AMSOIL

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.

I recommend Royal purple XPR, or amsoil zRod.

I put all the oils people be recommending into the ai to compare with the data sheat information from the manufacturers websites, amsoil still comes out on top ????

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

I just switched over to amsoil and my mpg went down marginally. Also using the PPE larger oil filter 10 micron filter.

I noticed when the castrol 508 spec wears. It smells Faintly of onions and beans. Strange smell indeed, when I took my car to street side VW out of Amarillo, Texas.
