Just wondering how often you all change your oil and at what mileage intervals?

I drive mine very little, change it once a year.

oldcutlass

I change mine once per year in the spring.

At what mileage interval?

oldcutlass

I never track mileage, but probably around 2500.

Got it..I've been changing mine every 6 months, and my last mileage was around 1000-1500 since I did it last...think I'll switch to yearly 😀

Once a year changes before storage would have cleaner oil without combustion by-products sitting in the engine and the engine starts on fresh oil. Old oil sitting in the oil pan would cause corrosion/pitting to the interior of the oil pan on marine engines stored for the winter.

My $0.02...

Every 2000 miles or once a year.

Once a year, in Nov or Dec, depending on weather as I’ll drive it in winter if the roads are clean. If weather doesn’t cooperate, it sits with clean oil in it.

Once a year on the cruisers . If I'm running a racing series like I did last year half way through I will change oil so every 6 races for cheap insurance on the street strip set up

Less than 1000 miles a year, I change the oil annually before I put the car away for the winter. It's usually as clean coming out as it was going in and that's how I like it.

If you're driving the car frequently, it's better to go by mileage. Most people here would probably go with a maximum of 3K between changes. Also depends on if you're using synthetic or dinosaur juice.

All of my vehicles are on a yearly oil change schedule. The newest vehicle recommends 7500 mile oil change intervals with synthetic oil, but I drive only around 5000 miles in a year.

Ha Ha.."dinosaur juice"...🤣🤣🤣

I use Valvoline VR1 10w30

Next time you do an oil change, consider sending a sample to an oil analysis company, the type used by owners of commercial vehicles.

This will tell you if there are corrosive elements in the oil. And for another $5 they will analyze to inform you how much life is left in the oil.

When I did this for my DD, I found that I could comfortably go 12,000 mi between changes--even when that constituted two years of service (although my oil tell-tale message comes up every 3,000 miles or so). However, I rarely drive that car on short trips, sump capacity is 8 quarts, and I use synthetic oil as the manufacturer calls for.

Hey now, you're depriving the oil change companies a lot of revenue with that attitude!

olds 307 and 403

I try not let my daily driver 17 Dodge Challenger GT go below 40 percent, which is usually 10,000 km with combined driving. Towing or more City driving lowers it, quite a bit. I use full premium synthetic 5W20, 0W20 in Winter. My worthless Dakota gets a spring conventional and winter synthetic oil change to help it start in -40. I get the fresh oil idea but up here it sits 6 months, not so fresh by then. The Olds is usually once a year, thr new motor will get many short, break in oil changes. I do the start up and make sure everything is running properly then once warm, then immediately drain and fresh oil and filter. I also leave non ethanol Premium 91 with STP additive/stabilizer over the Winter, usually top it up with a Jerry can of the same before start up. I am going to pay close attention to my outboard motor oil this spring for signs of moisture. I fog and cover it, do the same check over and immediate oil change once the cylinders completely clear out running fresh ethanol free Premium 91.
