Engine oil Castrol or PENNZOIL

PENNZOIL Engine oil

Older high mileage car: Pennzoil High Mileage blend. Works better for me than Valvoline MaxLife to reduce gasket seeping and weeping.

Pros: reduce gasket seeping

PENNZOIL Engine oil

I’ve been using Penzoil Ultra Platinum in my Jeep and it’s been running great, so far lol. The cold flow properties of the oil I use is really important because the winters here can be rough, thus why after watching that video I swapped to it.

Pros: running great, cold flow
Vehicle: Jeep

If you have ever rebuilt an engine that used Pennzoil, you would never use it again. The top of the head will be covered in carbon.

Cons: carbon buildup
