Engine oil PENNZOIL or RED LINE

Redline recommended 10w-40 Full Synthetic for my 1.8 solid lifter JH turbo application and the tech guy suggested modern synthetics don't cause seal leakage (like OG synths of 25 years ago) and holds up way better than the 40w rating in hot temps and protects much better when cold than even the current crop of Castrol 20/50 dino oil I was running. I swapped over the M81 to the same Redline oil and have not yet noticed any new oil leaks yet.

0W-30 VW 504 spec Penzoil Euro Platinum is all I use in my MK7.5.

Pennzoil has been pretty good to me. Not pushy.

I have a 16 with 110k miles and have consistently ran 5w-30 Pennzoil Ultra Platinum with no issues.

Pennzoil Platinum can be found for $26/5qt. and it’s certified to protect against LSPI. I’d suggest going that route if you’re trying to save some cash. I did and the car seems to love it.

I run Penzoil Euro Platinum 5W-40 because it's regularly on sale at Canadian Tire.

2010 Passat B6 with the 2.0T ea888 gen one engine. Different car, same engine. I run Pennzoil euro 0w40 in mine. 6-8k on the oil changes. Engine is quiet and smooth. 136k on it.

Just had my first oil analysis with penzoil platinum - black rock said I won’t need a change for around 5k miles with it

I've been running Pennzoil *Ultra* Platinum 5w-30 for the last 15k.

I use Madza OEM filter with Pennzoil Ultra Platinum 0W-20 every 8,000 km to 10,000 km.

I personally like the Pennzoil over the Idemitsu high moly oil but it's mostly due to being more available in my area.

I do think the Pennzoil is slightly better fuel economy wise and comes out cleaner than the high moly but this is probably a placebo than anything.
