But then we replaced it with a SkyActiv Mazda3 that used 0w20 and proceeded to have a good long history with that motor that had 0 oil consumption in 125K miles; I did all of the oil changes myself and it was always 4.5qts in/4.5qts out every 5k miles.
Pros: 0 oil consumption
Vehicle:
Mazda
Mileage: 201168 km
I run mobil1 but my local small engine place that installs and services Generac, Kohler and Briggs swears by Rotella straight 30 weight.
Pros: swears by Rotella
Amsoil. I run it in everything I own.
Pros: run it in everything
Mobil 1 . When my engines run smooth, makes it worthwhile. Any newly changed oil is better than any old oil. But Mobil 1 > Rest of ‘em.
Pros: engines run smooth
I run penzoil ultra platinum. I’ll spend the extra money to know that I might get a few more hours out of my gen.
Pros: might get more hours
I used to use German Castrol 0w30, then Belgian Castrol 0w40, now I use Mobil 1 Euro 0w40 in most applications. Intervals of 5000 miles Every engine I've had ran great under this regime.
Pros: engine ran great
Mileage: 8046 km
I highly recommend Castrol Edge 0w20 and Castrol edge 0w20 high mileage oil for your vehicle which requires 0w20 508.00 oil. 508.00 burns a lot. And I looked the additive in it. It is very cheap mixture. When I use regular Castrol edge it gives less oil consumption. Highly recommended for you.
Pros: less oil consumption
Cons: cheap mixture, burns a lot
I did the Marvel mystery oil 25% and drive for 300 miles engine treatment. While it did cut oil consumption by quite a bit, barely half a quart in 3000 mi now, it didn't take long for the CVVT solenoid to start throwing codes.
Pros: cut oil consumption
Cons: CVVT solenoid codes
Vehicle:
Toyota
Mileage: 175000 km
I will never use castrol again, stupid dark bottle is annoying and makes it hard to tell how much is left
Cons: dark bottle, hard to tell
Vehicle:
Mazda
