Change the oil before the vehicle sits, not after
Plenty of vehicles around Yuma do not run all year. A farm pickup used mainly in season, a second truck kept for harvest, a vehicle that belongs to someone who spends part of the year elsewhere. They work hard for months and then sit.
The question is when to change the oil, and the usual answer, change it when the vehicle comes back into use, has it backward.
Used oil carries the byproducts of the work the engine has done: combustion residue, moisture, fuel that did not burn, and acids that form as oil breaks down. While the engine is running, those are carried along and filtered. Once it is parked, they sit against the internal surfaces of the engine for however long the vehicle stays parked.
Fresh oil does not carry that load. An engine that is laid up on clean oil spends its idle months in far better company.
A short routine for a vehicle that is about to sit
- Change the oil and filter just before it is parked for the off-season.
- Fill the fuel tank, which leaves less room for moisture to condense.
- Note the date. Oil ages with time as well as miles, so a vehicle that sits for a long stretch is still due by date even with almost no miles.
- Check tire pressures before it goes back to work, and look for flat spots or cracking.
When the vehicle comes back, a quick look at fluids and belts before the busy weeks is time well spent. That is easily combined with scheduled maintenance, and any warning light at restart is engine repair, both here. The national oil change page covers what the service includes.
