Mix Havoline with Mobil 1?

[Woody]

Does anyone see any issues mixing Havoline 5W30 with Mobil 1 0W20 in either a 60/40 or 80/20 ratio and using it in a '03 Mazda6 2.3L (Mazda calls for 5W20). I've made the decision to go back to dino and have a stash of 0W20 I'd like to use up.

I'm mixing the Havoline 5W20 with Mobil 1 5W20 3.5:1 and a full bottle of VSOT.

Bump. Anyone have anything negative to say about this mixture?

Nothing negative just wondering why dilute the M1? All the accounts on here seem to indicate the Mobil 1 0w20 is a very good oil and since Mazda recomends 20W why not just run it until it's used up then switch to dino?

Well, call me paranoid. I'm getting concerned about the increased Fe in Mobil 1 used oil analysis compared to oils like Havoline and I'm planning on keeping this car a long time. I'm not trying to start a fire storm here either. Like I said, call me paranoid.

you're paranoid. your engine will not self destruct b/c of M1.
