Engine oil

[Peacock]

Oil needs to get hot enough to keep condensation down. I'm sure that 250+ is not an issue.

I think it's more of a problem with localized hot spots that cause coking.

I remember when the Mazda 2.3 came out in the Ranger in '03 or so. Used a ~230* t stat that had a small heating element that was used to control the t stat down to 190 or so. The idea was to optimize fuel economy and engine cooling for different scenarios.

To make a statement that ''oil is oil' Well, why not just use the the oil from the hamburger joint down the street ?

The oil is oil statement was made relative to a vehicle lasting its useful life and nothing more. Now it's repetitive use is really starting to expose the maturity level one gentleman who can't relate. I'm
kind of starting to get a laugh out of it to be honest. I didn't think anyone here was that slow...

So Kenmac. I have one question for you. Do you think synthetic oil is required to take a healthy (not out of whack) vehicle out past its useful life? If you answer no I rest my case. If you answer yes I think you would be saying that the SAE can benefit from your vast knowledge.

yea - hot oil temps are one of the places synthetics rule, anyone remember the early print and Tv ads for Mobile one.
where they placed dino and synthetic in fry pans and heated the oil, within a short time the non synthetic turned to sludge and you could still pour the synthetic, I think the same is true for really cold weather, no comparison for my old Ford tractor when running the 5-40 synthetic rotella verses the regular 15 - 40 Rotella cranking speed is much improved.

API tests conventional oil at 302 degrees Fahrenheit.

Just like any other product you buy, lubes are built for profit at a certain price. Some use cheaper ingredients so they can sell for less and some user better ingredients and sell for more. Which is more expensive, paying more for a better product up front, or paying for a repair that may have been avoided by using the expensive product?

In the average, older vehicle...NO.

In many current, past high performance or future vehicles....YES.

The OE's don't fill their crankcases with more expensive synthetic oils just because they read about it on the internet. They use the cheapest stuff that will meet their requirements.

Now, you try to clarify yourself to get out of the hole you have dug. "I didn't think anyone here was that slow"" NOW , isn't that calling the Pot calling the Kettle Black

Well I suppose after 32 years in the refining and marketing industry of the products within your area of expertise I think it's laughable that you think I consider conventional and synthetic oil the same. No, actually I guess I'm trying to "get out of the hole I dug". LOL.
FWIW, I think everyone here figured out my point within a couple of posts with the exception of you sir. My apology for that! I think you single handedly wore out my oil is oil quote while others actually contributed valid cases in which I AGREE (with some) there would be benefit realized from using synthetic oil. I can spell that out "Real Slow" if you'd like...
However, if I said synthetic oil wasn't a waste of money in the majority of cases in which it is used, I would be going against the education and raw data I've acquired throughout the majority of my life. I think I'll hold on to that historical and current fact.v
Actually, I predicted you would do a little bobbing and weaving instead of addressing my Yes/No question. Even brushing on "I know you are but what am I" mentality comments. I guess I got what I expected on that. Well anyway, the floor is still open on that one so please do provide an answer. If there's something you know that I may not I'm always willing to learn.

Other than that all I can conclude is that maybe the grass is a little greener on your side of the fence. Likely due to the abundance of fertilizer over there...

Enjoy your weekend..

Required... Really?

My wife's corvette was also delivered with synthetic oil but the manual doesn't call out for its use. When I return Monday I can scan and post that if you'd like. It calls for convention oil meeting the normal GM spec. If it was suggested for reliability or warranty I don't think the general would leave out that important piece of information. Future, well I guess only the future will tell.
BTW, the vette's been running dino. She has only about 45K but but UOAs are outstanding. Wear metals are well below u averages and nitrates are indicating the absence of sludge and varnish. At 10k recommended OCIs TBN is still 6-7 ish. Using castrol and I'm very pleased with the result.

That's the thing about the net. One can post my UOA's are this and that without posting the facts ! Let's see the facts of this great dino oil you speak of. Not just what you say. On my side of the fence ( where it's greener), we deal in real facts.You haven't said 1 thing that's believable. Get your facts and come back

I have seen this site many times. My E's father has used it to show me why brand X is better than brand Y many times. I can not tell you what makes one better than the other but looking back on it there is major differences in the additives. As Peacock mentioned, they all do the same job. And as I mentioned there are better products for the same dollar instead of just going with the brand that has the biggest advertising budget and brand recognition like McDonald's. Chris

I hear you loud and clear. Gonna side track for a minute... Warn vs Superwinch: people think warn is the best ever because of their monster advertising budget, yet Superwinch is just as good, if not better. But because they do not advertise the way Warn does, people think they are inferior. Not true!! Aside from Rotella, I do not see any other brands of full syn at Chinamart, could be a reason for this?! Hence why I rarely shop there!!
