I have a TBI Chevy. These are known for fuel dilution as it is. On top of that my work commute is less than two miles but I still idle my truck every weekday morning for 10 minutes to get some heat out of it for myself. Average morning has been 2-6 degrees so thats almost an hour idling in the cold (running extra rich) right there alone and the engine never actually get to full operating temp on my way to or from work.
I don't drive this vehicle much. Current PYB fill is at 5.5 months and just over 1000 miles. Besides my short work commute I almost never take it on the highway and its other trips are about 20 minutes long in mixed backroads and stop and go city traffic.
My point is, it's very low mileage but its some super harsh short tripping. I'm leaning toward running 6 month OCIs now regardless of mileage. Last OCI was 10 months and 3200 miles on VWB and the used oil felt like water. I've done quite a few oil changes and never felt oil that thin. Made me think twice.
So what do you guys think? Ridiculous to drain at just over 1000 miles or completely rational to drain potentally fuel and moisture contaminated dino twice a year?
