Engine oil Castrol or OEM Volkswagen

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

I have a 2024 Jetta S with the 6 speed. Mine used about a 1/4 of a quart of oil in the first 500 miles. I topped it off and it hasn't use any since, now at 5K.

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.

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'm at 308k miles and use cheap Castrol engine oil, house brand transmission fluid (the correct kind though), and the cheapest coolant I can find.

Had my gle350d 4matic oil change garage used Oil Designed for Ford cars believe it was A5 castrol

Nearly 3000miles later engine rattled. On stripdown found shell on crankshaft had welded to crankshaft. Eng report it was shell  slippage.
