I'm rethinking my approach to my oil changes with a '99 Subaru Forester (2.5L N/A Boxer) and have a question to ask the gurus...
I was wondering what the overall result would be by mixing 1 qt of M1 SM syn 10W-30 (non EP) with 3 qts of Supertech SM dino 10W-30
1) Will I fortify the dino by adding 25% synthetic base stocks?
2) The bottle of M1 states that it is fully compatible with other syns or dino...is this truly true or just a marketing gimick?
3) Am I wasting my money and overthinking this?
4) What major brand is a true synthetic blend that includes synthetic base stocks and not just synthetic additives?
Oh no...my brain just exploded from too many questions...
Truly I say thank you.
