I really don't see the need (in my case) running a heavy, super long lasting oil in the 2.5L VW 5-cyclinder engine. I don't do really long OCI and I think a 5w-30 would be ideal. My dealer used MST Valvoline oil (Weight unknown but I'm thinking 5w-30 since it's bought in 55ga. drums?) On ValvolineEurope website the SynPower IS 502 Approved. (Along w/the "FE" version.) What gives? Is the 5w-30 SynPower European oil different than the oil we have in the States? I've tried the GC 0w-30 and I like this oil but I've read it is on the heavy side of a 30w oil. Honestly, the engine runs like a dream w/the Valvoline as well! Just curious! Thanks and Cheers!
