Engine oil Castrol or PENNZOIL

Castrol Engine oil

I’ve been using Castrol’s 5w-30 with the RN0720 spec (for DPF filtered diesels like yours and mine), it’s the best oil for thins engine. 100.000km doing oil changes every 10k and it’s as good as new, very good fuel economy and no leaks

Pros: very good fuel economy, no leaks
Vehicle: Renault Clio
Mileage: 100000 km

PENNZOIL Engine oil

Just finished my break in on Fridays, did a oil change on Sunday with w5-20 penzoil platinum. But I honestly prefer you go with anything besides 0w-20, it’s good and the OEM spec but everyone has seen issues with that oil and it can’t hold well in hot temps which is what this car really is meant to be at hot temps

Pros: using w5-20 penzoil platinum
Cons: 0w-20 can't hold temps

PENNZOIL Engine oil

OP, love the choice of Pennzoil Ultra Platinum Ultra Synthetic! Anyways, does the jug of Pennzoil Ultra Platinum seem a lot lighter than other 5 qt jugs of oil?

Cons: lighter than other jugs

If you want to do 5k oil changes, best to switch back to Castrol GTX or any cheapo oil as you'll have no significant advantage using synthetic for short periods of time.

Pros: cheaper option
Cons: no significant advantage
Mileage: 5000 km

Castrol. I've just always used it. A bit of advice though, i'd recommend staying away from Pennzoil, I had to clean an engine out after using it. Nasty, waxy stuff.

Cons: nasty, waxy stuff
