BTW, that would be 262,144 times faster oxidation at 210 degrees than 30 degrees! So, happens at RT but almost at an imperceptible rate compared to 210 degrees.
Which are you asking? Your title says during use, but your question says sitting unused.
PimTac, you sure expect a quick response. I started this thread only a few hours ago! As my original question stated, I am asking about whether oil deteriorates, specifically oxidizes, while it's sitting unused in the vehicle. The thread title is appropriate, because if oxidation happens only during use, then it does NOT happen while the vehicle is sitting.Well, it appears the OP has left the building. We will never know what the real question was. Used or unused?

Thanks for the link, but can't we discuss this issue here as well? Is this thread offensive in some way?Five seconds on DDG.
Thanks, that was really my question. Would you say there is a meaningful difference between synthetic and conventional in this regard for a vehicle that will mainly be sitting unused?In general synthetics will resist stagnant oxidation better since they have more saturated bonds leaving less oxygen exchange sites.
Makes sense. I believe you've stated previously that there are other, more important, factors than dino/synth with regard to vehicles sitting unused. However, any reason to choose synthetic over conventional (or vice versa) for this application?It certainly does. For the purpose of defining a point, oil is "in service" once the seal is broken and its exposed to atmosphere. ( and its losing effect even before then albite slowly)
I believe it is every 10 degrees Celcius, not 10 degrees Fahrenheit.BTW, that would be 262,144 times faster oxidation at 210 degrees than 30 degrees! So, happens at RT but almost at an imperceptible rate compared to 210 degrees.

Thanks. Referring to a vehicle with minimal use, stored inside without climate control.Not sure what application you specifically are referring to but referring to dino v. S in terms of sump oxidation in general
I know of no reason either has a superiority in this category that I could promote with legitimate data.
10 degrees C = 18 degrees F. If your oil is at 210 degrees C you have bigger issuesBTW, that would be 262,144 times faster oxidation at 210 degrees than 30 degrees! So, happens at RT but almost at an imperceptible rate compared to 210 degrees.
According to Mobil temps of over 113F start effecting lubricant life.
