Oil Change Interval by Time, Not Mileage
Posted: Fri Sep 21, 2012 8:40 am
Since moving from urban California to semi-rural Arizona, my driving mileage has been reduced to about 3,000 miles a year as opposed to approx 12,000 miles a year.
In these 3,000 miles, the engine gets up to full operating temperature every time the truck is driven, never less than 10-15 miles, so there are virtually no "short trips".
I've always used Mobil 1 w/OEM filters and changed both every 3,000 miles (i know - overkill
).
What might be considered a good time-based guideline to change oil & filter under the current circumstances.
I don't know if oil deteriorates or loses it's capabilities over long periods of time.
Also, because fuel fillups are sometimes 2 months apart, might a fuel treatment be a long-term benefit?
I've never been a fan of additives at all, but under the circumstances..........
Any Thoughts?
