Hello, Excellent site you're got here! I was wondering what you experts think of this oil. Citgo Supergard Synthetic 10W-30. I was browsing around at Mills Fleet Farm and noticed it has an ACEA A3-02 and API SM rating. From what I've been reading ACEA A3 oils have an HTHS Rate of 3.5 or higher. This is 3.2, so is the ACEA A3-02 rating an older standard? ("02" as in year 2002?) I'm currently running Mobil 1 0W-40 in my 96 BMW 318ti and have no intentions of switching. Well, maybe the GC which is sold just a couple blocks away
Really just looking to learn!
