Engine oil RED LINE or OEM BMW
I have the 6.4 liter Hemi in my Charger, and I switched from Ultra Platinum to Redline. My car uses 0w 40, but nonetheless, I have not seen or felt any difference between the 2. If you are worried about switching, I can assure you that Redline is a very high quality oil.
I am running Redline 0w-30 during the warmer months. It was the most reasonably priced group 5 ester base (with great reviews) that I could find. Oil temps during my last autoX event were down 15 degrees F, compared to a similar day with the factory recommended 0w-20.
My 07 Passat has 236k. I change oil every 5k, cam follower every 70-100k (20k is serious overkill), lots of coil pack changes (like 4 or 5), and that is about it.
Redline 5w-30 with an OEM filter. No issues and smoother start up.
I recommend checking your oil level at 3000 miles because some vehicles burn oil. BMW and Audi especially, at 1500~2000miles I will top off.
Recently started using in my 2002 M3 and the oil runs cooler compared to the "twin power" oem oil i had been using.
Redline 10w30 full synthetic if I know I'm going to beat the piss out of it for the next 5k miles (think autocross or mountain runs), otherwise I use Honda 10w30 full synthetic.
I do not use auto oil. Motorcycles run hotter and I don’t trust car oil. I use Red Line. They sell a V-Twin kit that has engine oil primary oil and transmission oil, and fuel system cleaner. I buy one each spring.
Redline 5w30, the best
I've tested both those oils, and was not impressed with the results. Both oils still needed changing at 5k.
