Should diesel engine oil be changed after 1 yr with less than 100 miles on it

[navycamp]

I change the oil at least once per year regardless of not driving it. I have a 2006 with a great history and intend to keep it that way.

Hello,
On another note. It might be better for the truck to be used more often.
Keep it moving to stay loose like us.

Just a datapoint for the OP to make his decision.

I have an '06 Toyota Tundra that I now rarely drive. After 2.5 years and 3,000 miles on Mobil1 I decided it was time for an oil change. I also sent a sample out to Blackstone.

Here was their response:
"your 4.3 TBN means there is plenty of active additive to spare"

This TBN reading is actually higher than previous tests where I had 10k miles on the oil. Granted, those miles were accumulated over the course of a year or so.

[QUOTE=wagonmaster2;5674404]I changed engine oil on my 2015 diesel almost a year ago but due to the covid pandemic I've put less than 100 miles in several exercise drives. To keep my extended warranty happy would it be advisable to go ahead and change it again when the year arrives. The oil is hardly even blackened.


Seems a shame to throw away oil like that but I don't want the warranty company to claim I didn't follow manufacture's required maintenance, which I might probably be a good loophole for them to wiggle out of a claim.

wow i don't think that could effect the warranty. if it where thick an black like tar from neglect they may bring it up then. i don't think oil has a shelf life. i would run it, good luck

Have older 12v cummins purchased new. Now has 187000 mi. Change oil annually. Last falls oil change had 3000 miles. Sent in for testing. Report said, "Looks like an early oil change." I change because it sets in unheated building and am concerned about condensation.

I just would not want to say I followed the terms, when I hadn't regardless of the reason.

I would never buy extended warranty. Never.

Diesel oil is good for 15K miles. If you have an extended warranty do not cut corners. On one rv site an individual had transmission problem and they refused to honor repairs since he failed to have the oil changed annually. My extended warranty is long past so I do a major service every 3 years. I drive less than 5K miles a year but I still do the M1 services Annually .

It seems like some here are missing the big picture. An extended service contract that requires the holder to follow manufacturer maintenance requirements are not just concerned about engine oil and filter change.

You have three main components that I assume are being covered....the engine, chassis and transmission. Each one has many additional service/inspection requirements that need to be documented. I realize not all are an annual requirement.

For example when is the last time the following were inspected/lubed/serviced/changed on a coach that is approximately seven years old?

Fuel Filter Pressure Side
Fuel Filter Suction Side
Engine Drive Belt Inspecting
Alternator, Battery, and Starter Checking
Radiator Cap Checking
Radiator Inspecting & Cleaning
Coolant SCA checking (if required)
Coolant Change (if required)
Coalescing Filter
Air Compressor Inspection
Throttle Pedal Pivot Pin Lubricating
Suspension Fastener Torque Check
Suspension Height Control Valve Check
Suspension Inspection
Suspension U-Bolt Torque Check
Knuckle Pin Lubricating
Tie-Rod End Lubricating
Wheel Bearing End Play Inspecting
Oil-Filled Hubs Oil Level Inspecting or Changing
Axle Lubricant Level Inspecting or Changing
Driveline Lubricating
Brake System Valves Inspecting
Air Dryer Checking or Changing
Slack Adjuster Lubricating
Power Steering Fluid and Filter Changing
Steering Driveline Lubricating
Steering Gear Lubricating
Transmission Breather Inspecting
Transmission Fluid Level Inspecting or Changing
Transmission Filter Changing

While some might not apply to your configuration I would think a lot of them and possibly additional items would (I didn't even mention the genset).

If it were me and I was going to have the annual requirements taken care of as scheduled, an engine oil and filter change wouldn't be something I would even think twice about.

Really, are there insurance companies out there that ask for this?

5 years from now will it matter if it sat for a year and didn't have an oil change? I doubt it.

Insurance companies would be jumping for joy if customers put that few miles on per year.

Give me your money, I would take that bet.

The OP is asking referring to the requirements of his extended service contract holder, not vehicle insurance.

Same thing. Insurance is insurance.

This thread proves my theory, if you ask six people a question you get eight different answers.

I don’t have an extended warranty on my rig 2004 HR endeavor. I change the oil every two years or five thousand miles. I think the 26 quarts of oil can last that long. I take approximately two long trips a year. From Ohio to Florida in the fall and reverse it in the spring. The oil gets hot enough to get rid of the moisture in it. Each trip is about 1100-1200 miles for a total of 4400-4800 miles between changes. I like this schedule!

But if you want to change oil every year then go for it. You cannot hurt the rig by changing oil. It s cheap compared to the cost of the rig. It’s a free country (so far) if yearly oil changes make you happy then go for it! And if the warranty calls for it you can look them in the face and say “ heck yes I changed the oil every year” with a clean mind, keep receipts for everything as they will try to weasel out of anything that they can!

There you go one person two answers I hope this helps out the decision process.

Moisture in crankcase will disappear if started once in a while to warm up thoroughly. My farm machinery set 8 to 11 months between usage. I just add Isopropyl Alcohol to fuel for any moisture that might be in there.
