Title: Synthetic motor oil
Post by: TimRB on May 15, 2020, 11:30:55 AM
I keep trying to get you guys to talk about something other than C19, although I admit I have never considered the fact that underwear plus pants still don't completely filter a fart.

Anyway, I recently changed the oil in my pickup (Dodge 1500 gas), switching over to full synthetic oil.  Since then I would swear that the water temp is lower than normal.  My gauge doesn't have numbers (too confusing to the average driver, I guess) but it looks to me like the temp is about a needle-width lower.  If I'm not imagining this, it strikes me as being very strange, since the water temp is normally regulated by the thermostat and should be independent of oil type unless the engine is actually now not reaching full operating temperature.  Any thoughts?

I love gauges with numbers.  Analog gauges.  Old school Smith and Jaeger type gauges like they had in my old MG's.  My GUESS is that the synthetic oil is causing less friction and less heat, but your statement about the thermostat is true.  I am NOT a mechanic!

As a guess, I would think the synthetic oil is probably a bit more conducive to dissipating heat.

You bumped the thermostat when you were changing the oil.

Those type of gauges a barley a step up from idiot light.  So I would not have much faith in it.

Another possibility:  every time you changed the oil, the new oil allowed the engine to operate better... you just never noticed it.

Ohh, an oil thread! I love synthetics, I wish I could use them on my bike.

I'm curious why you can't use synthetics on your bike.

What bike do you own that you can't use synthetic oil?

I have a Honda CB1000r.  Wet clutch, you aren't supposed to use synthetics with them.  Bad juju, I think it has something to do with Molybdenum, but I'm no expert.  Couple motorcycle mechanics told me, so I stay away.

Synthetic versus non-synthetic oil has nothing to do with it. What it really boils down to, is, you don’t want use an energy conserving oil that is meant for automobile use in a motorcycle with a wet clutch.

What you want is a JASO MA/MA2 rated oil for your wet clutch bike. You can buy expensive bike oil if you like or you can find a well respected automotive oil such as Shell Rotella T6 synthetic. (Technically a diesel oil suitable for pickups). The T6 is JASO rated and bargain priced at your local Wally World.
