Engine oil PENNZOIL or OEM Audi

Pennzoil Platinum Euro 5W-30

Pennzoil ultra platinum. It is what they put in it from factory and it is one of the best oils around next to amsoil for a lot less money.

I know this is old, so you’ve probably already made your decision, but I use Pennzoil Platinum. It’s a great oil as well and tends to be slightly cheaper than the Amsoil.

That's what I run. It supposedly runs lighter than the specified 40. It's LL-01 approved. I change it every 8000km/5000miles.

The best performing oil for cold starts is probably Pennzoil platinum full synthetic if your particular prius uses 0w-20. It is made from syn gas, and is particularly thin.

For comparison, i got 6,000 miles out of Pennzoil platinum vs royal purple, with which i would get 5,000 miles prior to the oil changing color and about a 1 to 2 percent dip in fuel economy. Regardless of the wear additives, Pennzoil platinum lasts longer, again likely due to the cold start performance and the way the hybrid drivetrain works.

Haven’t heard anything like that about Mobil 1, but I personally use Pennzoil Ultra Platinum 5w30. It’s performed spectacularly for me.

Penzoil Ultra Platinum will be on a entire different level. Stuff is amazing.

Penzoil platinum held up nicely. A hair thinner and less active additive than Valvoline but wear looks great.

I don’t drive my car enough to hit any of the reasonable mileage points. I change my oil yearly, roughly around the time it gets inspected. Might be overkill (last year the car moved 2k miles, the year before was 2.4k), but I figure the $80-85 I pay is worth it. My wife’s Q7 will be getting its oil changed every 5k miles. It’s a 3.0T supercharged and they love to eat oil, I’d probably add half the oil back just to make it to 10k.

I do every 5k (2013 S4)
