oil change... time vs mileage

FWIW, My oil and filter change schedule is: 6-months or 5,000 miles.

I'm only putting about 10,000k miles per year on my truck these days. imo,That's too long of a time for contaminants to be hanging around in the oil, especially during the winter. About 50% of those miles are fairly short trips. This can contribute to fuel, water and other contaminants building up in an engine and the oil that likely doesn't reach the required temperatures to warm up enough to completely drive them out. The oil-changes are usually timed to take place in October and April regardless of miles. (usually works out to around 5,000)... Nice fresh oil for the duration of the tough cold winter and hot summer temps and conditions is what is the most important for me.

YMMV

 

Sounds like a well thought out plan.

 

5-6,000 miles or six months.

 

I change mine once a year because I don't put many miles on it.

 

5k, full syn, OEM filters. All four vehicles.

 

Every 5,000 miles on my 2010 regardless of time. This has come out to only once every 2 years for the last couple oil changes. Always full synthetic 5-30 with an OEM filter. The truck has 171k miles on it and I bought it in 2019 with 148k. I normally go every 10k on the Prius as Toyota recommends.

IMO changing the oil every 1,000 miles is totally unnecessary unless you're just flogging your truck on a regular basis. Especially with a good full synthetic.

 

I do 5k/year these days, plus I have 2 other vehicles.

Mobil1 synthetic 5w30 and an OEM filter is good for me. I should do a Blackstone test just to be sure

 

Mobil 1 synthetic is more than good enough for 5k miles.
