Synthetics are inferior.

sprintman is right on the money. LE know their $hit.

Their LE607 gear fluid is the only thing I'll use in my S2000's differential.
 
I don't think many are doubting LE products (although most folks don't of know them) - it's the statement...."fall to the bottom of the pan"..... sounds like the guy will say anything to trash the competition.
 
Just like Ethyl Corp---because LE is "big" and becomes "influential" doesn't automatically implies that they know their $#hit. Afterall, the bigger the company these days, the more they would try to alter/steer/drive customer's decisions in a rather arrogant way.

My 2 cent's worth
 
For most applications, most of us do NOT need synthetics unless you are A.) Extending drains B). Live in the North Pole C) Race and see high engine temps. However, his statements I have never heard of and would need to verify them.
 
Does this effect how we take an oil sample? Should we drain the bottom have of the sump into a clean container, stop, drain the rest into the recycle drum, then put back the first bit, and top it off? Were's Gary Allen, this sould like an application for one of his filters, but mounted vertically so the depleted oil on the top can be seperated. Oh, Gary......

Yep, thats what a salesman from LE told me today. What happens he said, is that synthetic lubricants just do not hold their additives in suspension and they all fall to the bottom of the pan where they just sit doing nothing. "Our regular oils are FAR superior to any synthetic oil" "Our additives stay in suspension and are good for up to 1500 degrees, synthetics don't come close" I was thinking next time I have an engine that encounters 1500 degree oil temps. I would use their oil. hehehe

Did the salesman happen to be wearing a home made foil hat to cover his head with?
 
Perhaps a time warp

Supreme Engine Oils are recommended for use in veteran, classic and vintage cars, motorcycles and tractors, where engine design and tolerances prohibit the use of modern multigrade, high additive level oils. Modern dispersant additives keep combustion chamber contamination suspended in the lubricant, allowing full flow cartridge filters to remove it. Early oil filtration, usually in the form of a mesh gauze or strainer, is not efficient enough to remove this suspended material. Supreme Grades are low dispersant oils and allow the suspended matter to drop harmlessly into the sump.

I once read somewhere that mineral oil are superior to Fully Synthetic in their ability to suspend soot. A major concern in diesel engine.

Respectfully, I've seen it and don't buy it at all. We have too much evidence to the contrary right here in our own UOA section. Let's see, a guy who makes money doing maintenance work, including oil changes, recommends a 2k OCI -- I smell a large, fat, cash hungry rat. . .

With respect to LE, let's not forget that even the best companies will often have a goofball or two (or more) on the payroll.
 
Wish I could afford LE as it would be my oil of choice along with Redline. I realy don't understand how this company, so well respected worldwide is basically unknown by the oil cognoscenti on BITOG. Must be poor marketing or something in North America?

I don't know about way back in the past, but today, you buy a different oil for diesel engines and it's different from oil used in a gasoline engine. You can get both regular and syntetic oils made for diesel.
 
I know 2 folks who used to work for LE. They both state that it is a good product, but not as good as the good synthetics on the market.
It is not mass marketed in the US-they have reps, primarily aimed at fleet/industrial use.
 
If conventional oils are superior, why would anyone ever make a synthetic oil? On top if that, if you haven't noticed, synthetic oils are more expensive. Maybe the statement should read, "In non-stressed applications, good weather, normal driving, 5k oil change intervals, conventional engine oil is more cost effective than synthetic engine oil". And this would be especially true if you need to keep up with warranty requirements, and you keep the car three to five years and 100k miles or so. Or, should I just keep on fishing?

LOL...

"To support our theory, we have had oil samples tested in control lab settings from different vehicles for varying lengths of use. The results indicated even the highest quality oils’ additive package was used up at approximately the 2,000 mile mark."

Love to see the test results to back-up this B.S.

If the additives are gone by 2k, why would he recommend waiting until they are gone to change. If he is right, we should be changing our oil every 1,500 miles or even 1,000 miles, so we are o nly using oil that has some additive strenght left. This guy sounds like Mell Brooks version of Moses. "*** has given me these 15...oops... 10 commandments".
 
sprintman why your oil of choice? Have you ever used it? How do you know it's good?
