I’m new to BITOG. Was a 25+ year BMW-only owner, but got frustrated with their engineering/design choices, so in 2017 I bought a 2017 Miata (LOVE it), and late 2019 I bought a VW GLI (boring) for my wife.
Both cars spec 0W20, as you know. I drive’em like I stole’em, so that spec doesn’t sit well with me. I swapped to Supertech Synth 5W30 for the Miata, and M1 0W40 for the GLI after the factory fills. After this OCI, I will consolidate and give them both a VW 504 - haven’t determined which one, just yet.
One thing I immediately noticed in the GLI, going from VW 508 to VW 502, was a 10-15 degree drop in highway oil temps. 508 would stay at 225 degrees, climbing to 230 in city driving. 502 stays 210-215 on highway, with 225 in city.
Anyone have a favorite 504 that they recommend?
