OK here’s the question…
As the temp is dropping (like a stone) I’m losing my guts to run Mobil 1 out to 7,500 miles as I had planned.
Most of the driving in my 2 vehicles is relatively short hops - say a 12 mile run in the morning and a 5 mile run in the evening for one car, the opposite for the other (sharing daycare pickup duties with the Mrs.) On one car there’s more errands etc on the weekends, but still mostly 'shorter' trips to the store etc.
I’ve got M1 5W-30 in my Chevy with the 3.4L V6 and M1 0W-20 in my Honda Odyssey with the 3.5L V6. Filter is Acdelco / Wix/ Purolator…
Is running Mobil 1 ‘only 5,000 miles’ really stupid? 6,000 miles? Beuller? I had considered 7,500 miles to be the ‘minimum’ interval for a high-quality synthetic but now getting the cold feet (literally and figuratively). I have all these visions of nasty crud accumulating in the oil.
The rest of my ‘maintenance schedule’ for these rides is pretty conservative (ie Transmission, coolant, brakefluid etc), just wondering if I’m going ‘way overboard’ instead of just ‘overboard’ if I shortened up to 5K miles. Money isn’t really the issue since I do the work myself. Just don’t want to feel dumb while I’m at it...you've heard of "compassionate conservatives",well I want to be "consistently conservative"!
Not sure a UOA would make me feel more at ease, since the ‘variables’ are always changing. Plus, I’m not sure where to set the bar for UOA results - what's good enough?. Guess I'm just looking for the optimal 'no brainer' OCI without running Mobil 1 3,000 miles
Or should I just run a good dino (5W-30 and 5W-20 as appropriate) every 3,750 miles and call it good? Haven’t heard anybody yet say that was a bad plan.
Sorry to beat this dead horse. My shrink is off for the holidays so y’all are my only hope.
