Engine oil PENNZOIL or AMSOIL

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.

Switched to Amsoil awhile back and have no regrets.

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

Amsoil Signature series 5w30 is one of the best oils you can get that meets the oil specifications

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

If you want oil that has zinc, close to the oe oil weight, and is really good I'd go with ams oil, it is expensive but after 3k miles mine is still really clean

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.

Honestly I wouldn't have the guts to run it for that long. I run Pennzoil full synthetic with a Purolator boss filter and I still do changes every 5000 miles.

I have been using AMSoil for years and did the once a year/25k miles oil change for years and and my engines have had zero issues.
