I'm trying to decide which oil to use to take advantage of FCP Euros lifetime replacement program which includes motor oil. I'm currently running the LiquiMoly Leichtlauf 5W40 but FCP also has a LiquiMoly SpecialTec LL in 5W30 for the same price. Looking at specs, it looks like they both have an HTHS of 3.5. Wondering if I should just stick to the 5W40 or try the 5W30. Both oils have the LL01 spec.
My N62tu is almost at 180k miles and I change the oil two times a year regardless of mileage. The only area currently leaking oil looks to be the oil pan. All the other common leak points on this engine have been remedied. My car doesn't really see short commutes so the oil generally has enough time to warm up.
