Color has nothing to do how well an oil performs.RaideRNatioN said:Since my wheeler is not the DD, I havent changed it since last April. Granted Ive only put maybe 2k miles on it. Its Mobil 1 and I have the oversized filter as well. I checked the oil the other day and it was still in pretty good shape. Ill probably change it in the next couple months.
Its all about oil analysis then go from there. 15K-25K is a pretty long interval but its do able i would never go that long. I go every six months between changes, no oil analysis yet.Tufemup said:How long do those of you run running synthetic oil go between oil changes? Most brands claim you can run 15 - 25,000 miles or one year between changes.
But that's assuming conventional oil right? Synthetics last much longer and your genious Japanees engineers didn't specifiy dino or synthetic in the manual.fast frank said:Those guys (The ones that designed my motor) say to change my oil every five thousand miles.
Totally agree.... I change mine at 3,000(on my Dodge Ram with Mopar filters).fast frank said:I change my oil and filter every 5k. Period.
I'm running Mobil one and using Toyota filters.
Wouldn't that be a filter issue then?Janster said:Totally agree.... I change mine at 3,000(on my Dodge Ram with Mopar filters).
The synthetics (Mobile 1) will last a long time and usually don't break down like conventional oils can. BUT they get dark as crap which means the oil is DIRTY. Synthetics are known to keep the engine cleaner and remove/prevent sludge buildup. Keeping the oil in there for extended periods of time, you're just recirculating that dirty oil and it'll keep getting dirtier and dirtier.
