Hello all,
In my 1983 Ferrari Mondial QV, the spec is the outdated synthetic 10w50 AGIP oil but many owners have switched to the Valvoline Racing 20w50. I have a California spec car with an air pump and two cats and I'm just curious how the super high zinc oils like VR1 and M1 15w50 will do with that content. I plan on keeping the stock cats until they die then go with some 200 cell Fabspeed units but so far they are still within spec and passed their last emissions test in CA before the car moved to Alaska. The car has been running Shell Helix HX7 synth 10w40 since 2017 but I'm looking to go up to a 50 or 60. Any recommendations for a good oil that would meet the spec but still be friendly for a 85k mile street car with emissions intact? (Preferably from those with firsthand experience)
