Engine oil PENNZOIL or RED LINE

I use Redline 5w-40 because I noticed my engine burns a quart every 2000miles using other brands or thinner grades. With RedLine there is barely any consumption.

I’m running Penzoil ultra platinum 5W-30. The instructor I drove with said he runs 5W-30 in his gen 1 BRZ track rentals.

Have an 07 Silverado bought new first oil change switched over to Mobil one used that until one of the hurricanes hit Louisiana and started having a problem getting it so switched over to Pennzoil full synthetic. Truck has 368000 on it and seems to be still going strong so I’d say it’s your choice.

I use Pennzoil Platinum. Is it the best? Who knows, but I’ve been using it for years on several vehicles and never had an issue.

I’m using Pennzoil Ultra Platinum, really helped how effortless my acceleration is and gas mileage.

I run Red Line oils in my H-Ds and Indian.

I tried to use the Pennzoil high mileage full synthetic the most, but if I didn't have the bit extra for it, I'd get Walmarts generic full synthetic high milage. I always used a Fram full synthetic filter too, they were the only ones around me that were better quality and decent price for the time. Mine got to 200k no problems!

Started running penzoil platinum in my mazdaspeed due to the great UOAs it got on DI motors, and just now run that in all my shit to simplify my life. Only have to keep one oil around that way.

Get the Redline 5W-30…you won’t be disappointed. I was floored by how much better my Z performed with this oil. I’ll never use anything else.

So when i changed the car to 10w40 redline I noticed that the car began to knock around 3-4k which it didn't do before and now it seems to slowly get worse.
