Engine oil VALVOLINE or PENNZOIL

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.

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.

Pennzoil platinum high mileage full synthetic 5w-30. I work at a Toyota dealership and this is what we use and is recommended. It's flows well and has great wear protection. I used to use mobil 1 but this stuff is 10x better. If you do a little research it shows this stuff performs/flows better then most oils.

I run Valvoline VR-1 20w50 in my '74. It is straight Dino oil but it has a higher amount of zinc in it which solid lifter cars like ours love.

Pennzoil euro platinum LX 0W30 is the only readily available one that has the fiat/API approvals for the engine, advance auto usually has in stock at most locations.

I'm partial to Pennzoil Platinum Ultra 5w-30 based on UOA's at Bitog and other internet sources...

Valvoline max life kicks ass.
