I don't see delvac 5W40 in the list. Where is Doug?

If delvac can't save this engine ...somebody in Germany made a big mistake designing it.

 

[oilyriser]

Good ? about recycling this stuff. I'm sure it would make an excellent furnace fuel, but can it be purified for re-use along with used conventional oils, or does it have to be collected separtely?

I am very interested in this oil. I do have a very important question though. The 5w-40's viscosity at 40deg is higher than some 15w-40 oils. Most 5w oils have a viscosity at 40 at somewhere in the 50's and not 90s? Can anyone explain that?

This is a table of oil viscosity and fuel dilution measurements made across 16 different Audi RS4 engines, with various oils, most of which are Audi/VW 502 approved. Can you guess which oil remained in grade under heavy fuel dilution, extreme driving, and even racing conditions?

I have no doubt about your word on being fuel dilution resistant. But my question is still unanswered? Why is the virgin oil has a viscosity of 90 at 40deg being a 5w, when most 5w oils at 40deg have a viscocity of 50-60? The Amsoil AME 15w-40 has a viscosity of 89 at 40deg.

I am not doubting this oils capabilities, but why didnt RLI just call this 15w-40, cause i don't see any 5w property?

This is incorrect. Most 5w20 and 5w30 oils will have a 40C vis of 50-60. A 5w40 is going to be in the 70-100 range. A 15w40 is going to be in the 90-120 range.

Examples: Mobil 1 5w40 has a cSt of 102 at 40C. Shell Helix Ultra 5w40 has a cSt of 76 at 40C. Why the large difference? Because the Mobil 1 is blended to be quite a bit thicker than the Helix. The 100C vis of the Mobil 1 is 14.8, while the Helix is 13.8 (putting it on the low end of the 40 wt range). The Helix also has a much higher VI (187) than the Mobil 1 (151).

 

[Lonnie]

That is an amazing performance for RLI, the blue/green rows. At this point it does not matter what the secret 502 spec's are, I think you guys have solved the problem. This chart is a good indicator of that.

So is it that the Amsoil AME 15w-40 is just a thin 15w? Cause its viscosity at 40 is 89. It just seems as though they could have called this 10w-40 or 15w-40.

The vis at 40C is irrelevant for labeling an oil 5wXX or 15wXX. It's the cold cranking and cold pumping vis numbers that determine the "w" number.

Here are the VOA viscosities of two other oils that are not 15W40.

Elf Excellium LDX 5W40 83.8 @ 40C .. 13.6 @ 100C
Motul 8100 Etech 0W40 72 @ 40C .. 11.8 @ 100C

As G-Man says, it's the cold cranking and cold pumping performance that determines the lower viscosity designation.

 

[bruce381]

canyou redo this list without the 40C colum and put in a Vigin 100C vis to see how the oils "faded" that would be much more informative.

Renewable means that the oils are derived from resources than can be regrown, as in "wood products are made from renewable resources."

Biodegradable means that the oil will break down into its basic elements by UV (sunlight), bacteria, heat, etc.

Impressive specs for a 20wt.

Dear Bill,
This is the easiest testimonial I can write. Since switching our car to Renewable
Lubricant bio-based products, we have seen an increase in engine parts life –
bearings, lash caps, rocker arms. We have seen an increase in parts life by an
amazing 300%.
Our engine bearings – by far the most abused parts – last race after race. Our
rearend gears – same story. Our 3-speed Lenco transmission looks so good that
Lenco technician, Matt Moore, says he would like to recommend all racers use
Renewable Lubricant’s transmission oil.
We won our 5th World Championship totally lubricated with Renewable
Lubricants. In 2000, we set a new world record in Rockingham, NC at 241.77
MPH. Besides the performance end, it is very, very safe to use. The flash point of
Renewable Lubricant’s oil is much higher than that of petroleum based oils. This
gives me much peace of mind in the event of a crash or a broken oil line.
We, here at Mark Thomas Racing, can claim the winningest record in IHRA
history. A lot of our accomplishments could not be possible without the reliability
of Renewable Lubricants. I could race without Renewable Lubricants, but
certainly do not want to.
Sincerely,
Mark Thomas
Mark Thomas Racing, Inc.

Those 0w-20 specs do look really good on paper...

[LINK REMOVED]

fyi, they have updated their website with pricing and ordering info. They also make a 0w-30 with incredible specs.
