Engine oil PENNZOIL or IDEMITSU

I don’t use the Mazda-branded version, but Idemitsu is my go-to oil in all of our Mazdas

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.
