Engine oil Castrol or Pentosin

this oil is my most trusted, been using it since new with the best results ( i tried Mobil1 0W40 and a 5W30 Total Quartz once each and oil temps were 15-20 degrees hotter in similar ambient temps and conditions with both of those so i decided not to use them again).

They also have the 5qts of Castrol Edge 5w-40 for under $30. I've been running that in my cars since 2005.

Last change I did was with Castrol Edge 0w-20 no issues.

I've always run conventional Castrol 20/50 in my Gti's (past and current Turbo) without issue.

Castrol Edge 0W40 A3/B4 (European Formula), about 27$ per 5 quart jug at Walmart. Made in either Germany or Belgium. A real synthetic, Type-4 PAO based (no Type 3). Meets the strictest oil requirements from ze Germans.

12 Galant 2.4 always running Castrol edge 5w20 and oil filter change every 5k miles for like 60k miles now has 126k. Cars have never shut off or left me stranded or left any signs of hesitation.

Generally, brand matters a lot. Amsoil, Mobil 1, and Castrol are all great.

I run Castrol in my older cars and Mobil 1 in newer cars that I care more about.

I usually change the oil every 7500 miles and tend to use Castrol synthetic 0-40.

I just use German made Castrol Edge 0w40 (502 certified) oil. Ive used this oil since the car had its first oil change and it does not burn a drop and car runs great, i now have 59k miles and shes drives new as ever.

I spent ages today on the phone to numerous SEAT dealers, VW dealers, SEAT HQ, VW HQ, Castrol and Millers. The bottom line is total confusion everywhere. I rang 12 SEAT dealers - all but one (I'll come back to which one)said that VW 505.01 must be (and is)used.
