I’ve been researching online, and have found a full range of answers by “internet professionals”……but I thought that for a reliable answer backed up by people who actually know what they are talking about, this would be the best place to ask the question.
Long story short….I’ve got a twin turbo BMW N54 Inline 6 in my “weekend” car. I’ve always ran Rotella T6 5w-40 in it with a Mann filter, and change it out every 3K miles (oil is cheap, motors aren’t). The car has around 100K miles on it now, and over the winter I’ve been doing some work on it….bigger turbos, and running on e85 now. The new turbos will make around 27psi boost, and should make close to 650+ hp at the crank. It doesn’t really spin crazy high rpms (shift at 7K), but it makes a lot of torque (550+ ft/lbs)…..so these motors are typically hard on rod bearings.
As far as oil goes, am I’m ok to keep running the T6, or would I be better off looking at some of the boutique oils out there? I saw that Amsoil has a “boosted” series of oil for turbo cars. Liqui Moly, Motul, and Redline also make some oil that they market towards turbo cars. After all the money I invested in parts, I don’t mind spending a little more on oil if it’s actually going to help protect the motor a little more.
Any info would be great! Thanks!
