How many kms oil change?

[the big wheel]

So many different oil change intervals
When you ask even dealers of the same brand
Use synthetic oils in all halftons and cars.
Filters say 16,000 20,000 oils say high kms
As well. Change at 7,000 km don’t really watch the
Percentage monitor.

Even the Diesel engines in equipment
John Deere super plus says way more hours than
We go.

10,000km for gas vehicles with synthetic oils
Once per year for small motors (auger, water pumps)
350 hours on diesel motors 2008 and newer, 150 hours on older, running JD oil in everything

Been no blowups, so sticking with this program.

I thought the introduction of EGR emmisions technology warranted shorter oil charge intervals?

Bigger oil pans.

Bigger oil pans.

In 9870 manual gives interval based on oil pan size. JD oil is 1.5 X hours. 2016 Cummins says 500 hours, uses NO oil in 250 hours. Paccar says 40,000 Km on highway, we do 20,000 short haul/idle. Been doing Oil sampling since 1990, most okay, saved a few bucks overall. Best samples was MBE 4000 Mercedes, nothing else close, after 17000 km excellent. Worst was a new Duramax, full of wear particles. New Cummins 9 L is terrible also.

On our GM vehicles we go as oil minder says, 7-8000 km on SUV is about 20% left.

Usually ~7K on gas pot personal. I do go by the % monitor and usually run it to about 30. So if we do a bunch of highway miles it can get up to 9500 or so.

125-150hrs on older diesels.

250hr oil changes on 05 C15. When I ran highway I used to run 250hr filter changes, and 1000hr oil changes. Oil samples sent away every 250hrs, and unless there was a problem I left it in. That was full synthetic 5w40 with a 9000 series fleetguard which has bypass filtration.

One of our 1974 model tractors just rolled over 10,000 hours. It has had an oil change almost every 100 hours since new. At 12 litres of oil per service, that is 1200 litres of oil. Adds up after a while.

Diesels with hour meters that count key on time, I change some time after 250 hours. Older diesels with Actual tachs giving full throttle hours, 100 to 150.

Gas automobiles, when I get time, which isn't very often...

None so far…

What does everyone do with oil changes on engines that dont see a lot of use? Generally have been changing when needed or annually but just looking at hours again and wind up with 100 hrs usage on engines that call for 250hr intervals? Tandems and swather for me dont get houred out. How extensive is oil breakdown just sitting over winter? The one truck I just checked has 115hrs and the oil looks like it was just changed.

If you are worried about it, just start the engines every 2 months and evaporate the oil that condensed in the oil pan. Lots of tillage tractors get parked at the end of may and not started again till august for a grain cart. Not really much different than the stuff parked over the winter. There is no real difference on longevity for machines that oil changed before winter vs in the spring or summer. Lots of personal beliefs, but absolutely zero science to support either side of the oil change arguments. Most engines just say change at so many hours. They have eliminated the words "or annually" on engines.

The truck went about 5 years on a 1000 miles.

Wonder how many use 5/40 synthetic in diesels
Year around? I use it in machines that run mostly
In winter but sometimes summer. For other equip
Run 15/40 summer and winter if not used a lot in winter

15/40 synthetic year round may be the answer? Good
Pour point in winter and heat protection
In summer?
