TOPIC:

Synthetic oils are a whole different story. There is no VI improver added so there is nothing to wear out. The actual oil molecules never wear out. You could almost use the same oil forever. The problem is that there are other additives and they do get used up. I suppose if there was a good way to keep oil clean you could just add a can of additives every 6 months and just change the filter, never changing the oil.

I'd be willing to bet that there is more than enough room for 6 tiny ounces without causing any foam at all during the few seconds it takes for the pump to fill the cooler.

LOL This post had me rolling my eyes too.
Full synthetic oil has been called too slippery for a roller bearing motor , but to fast to allow cooling in a oil cooler ??? That's
a new one on me

Fluid is fluid. Some do cool differently however. It would be interesting the heat dissipation figures between the two.

Pretty sure the synthetic oil comment was a joke.

I got that
, But it does make for a interesting debate,
Less friction at a given pressure equals increased flow,, Gallons per minute up for thinner oil weights, or same weight , but slicker on a molecular level.
And that being said do you compensate with a larger cooler for the faster flow
Have Fun
Dave

Nah, you don't need to compensate for the faster flow through the oil cooler because the oil shoots through the engine faster too, so it never gets very hot. Ed

Actually, synthetic oil is not more "slippery", it doesn't reduce friction other than when you are at meltdown temps or on an extended change interval. Performance wise synthetic is pretty much same as mineral oil, it just lasts longer and holds up to high temps better.

So , then the reports that full synthetic oil can be a problem with roller bearings is false ??
The word is that on a roller crank and rods the rollers in their cages were slipping on the races versus rolling on the races causing galling of races and early bearing failure . Do a google search on the topic and let me know. To throw more gas on this fire , this debate became huge when Harley started putting Full Synthetic in their motors and transmissions from the factory and it caused issues. .

Again , This is just a for fun debate. I prefer Regular oil , ( Shell Rotella ) .
Dave

It is also more resistant to shear stress, which is good in a transmission.

I must admit this has turned out to be more entertaining than I expected. I'm glad I decided to quit posting in it.
