Car not run for 9 months - Oil still good?

Valvoline Synthetic Extended Protection 5w30

My car has been sitting at the shop for 9 months (electrical issue). 1800 miles on the oil when I dropped it off. During that time, the car has only run intermittently for a few minutes and very infrequently; it has been parked outside from late summer through mid-Winter.

Any issue with sticking to a 5k OCI? Any risk? For example, would moisture be an issue?

 

[Furious]

Moisture could be an issue, I would not take any risk and just change it.

That would be my inclination. Seems like cheap insurance. But I don't want to be wasteful.

Why are you letting a shop take 9 months? After 30 days I would have pulled it out of there. The depreciation on a 2019 Genesis for 9 months must be $2-3K alone.

Yeah, not happy about that. The work is under warranty, and this is the only Genesis dealer near me.

Yea but it would be pretty wasteful to possibly cause excessive wear or lose a good engine. Oil is cheap.

Did they give you a loaner for this whole time at least?

Yep, I drove the G70 and G80, both AWD. The '21 G70 had the same 3.3TT engine as my G90. The '22 G80 had the 2.5T engine. All nice cars, but the G90 is the smoothest.

True. I am still curious about the risk though.

 

[Furious]

The risk is probably minimal considering Valvoline Extended Performance is an excellent oil and a nice drive would get rid of most moisture, but it isn't a risk that I personally would take.

Run it. Doubt any appreciable amount of moisture has built up in the crankcase.

 

[JHZR2]

If you want to be rigorous vs speculative, pull a sample and do a UOA to look for moisture and fuel.

Dubious any trace of moisture is there. Even if there was some, the oil is designed to disperse it, so not an issue.

 

[Lubener]

I wouldn't worry about moisture. If there were some, it will quickly burn off with a good run. Then find a new dealer.

 

[demarpaint]

Take the car for a nice long drive, at least 30 minutes on the highway. That should take care of any moisture, then look for another dealer.

 

[Eddie]

+1 on a 25+ mile highway drive. If possible, find another reputable shop.

 

[aquariuscsm]

Only 1800 miles? Oil is still bad new. No worries.

 

[kschachn]

Oil does not go bad just sitting in the sump. It won't cause excessive wear and it won't damage the engine. Any "moisture" needs the products of combustion to create acids and even so the oil will buffer those.

I now run my cars 5k unlimited years due to the high oil prices. I have a fill in my 2000 crown vic that has 2600 miles on it from 2019. Still looks golden clear and no moisture. I do however use that car for long trips.

 

[Wheel366]

The oil I have in my S4 probably has less than 1k miles and has been in there for at least 4 years now, if not longer. If I were to guess, I would say probably less than 500 miles. My reason for not changing it is because I don't drive it at the moment. Once I get it re-registered and inspected I will probably change it. I do run it every 6 months and if I can I let it run for a while and even give it some gas to get the oil temps up around 200-225.

No problem. The Oil is stable and fortified to neutralise acid formation. There is always moisture getting into the oil. A good hour drive and the PCV system will steam any little bit of that off

No "cheap Insurance" here - just a waste if you change it.
