New SFR 100 thread

[Ray S]

I have used Finish-line grease for years on my bikes based on these tests
http://www.sandsmachine.com/grease_t.htm pic
which Sands Machine have been doing for ~20 years, and explicitly stating they are only valid for high pressure galling wear.

Their runner-up is SFR Superior Friction Reduction Oil Fortifier - a (pricey) liquid rather than grease. The diesel version is at least available in quarts, and has an MSDS https://www.sfrcorp.com/public/msds/D-SOL_SDS.pdf "Mixture of hydrocracked Hydroisomerized Group III , Magnesium sulfonate" so at least some info there.
I've never bought SFR, but thought I'd stir the pot since other old threads are locked.

Just looked again at https://www.sfrcorp.com/product/sfr-ultimate-series-diesel-motor-oil-15w40 as BITOG seems to like Rotella and diesel oils for older flat tappet motors.

Also some disparagement for the wear tests of course https://www.falex.com/wp-content/uploads/2016/12/FalexPinVeeBlock.pdf
as relevant to engines.

Usually the engine out lasts the chassis unless garbage quality parts or an assemble problem occurs. The only passenger car engine failure I ever had was a 1987 Olds with the 3.8 engine running Amsoil. They left out the cam button with the roller cam and it ate the timing cover which filled the engine with aluminum shavings, Amsoil didn't stop the engine failure nor would I have expected it to. I just can not get too excited about engine oils claims.

I'd think that anti-galling properties would help with "dry" startup of tappets, or allowing one to run lower viscosity oil and consequent thinner film on walls and shells.
As far as oil in general the add-pack and base stock is certainly key - and that is not specified by SFR. However, the "fortifier" https://www.sfrcorp.com/product/d-sol-synthetic-diesel-engine-oil-fortifier
I presume is in their diesel oil does have a blurb:

SFR's synthetic fortifiers contain organo-tungsten with special alkylated diphenylamines for deposit control at elevated temperatures, which improves oxidation stability and drain intervals. D-Sol has a very low friction coefficient to reduce wear significantly over regular motor oil. Diesel engines, with the creation of soot, need additional detergents than what is required for a gasoline engine. For this reason D-Sol has more detergents than Gaszol to fight soot deposit accumulation.

Testing has revealed that tungsten has excellent anti-wear properties over molybdenum (moly) and being a transition metal actually bonds with iron to form a smoother surface. For the ultimate in wear reduction use D-SOL in your diesel engine with each oil change.

But, non of the MSDS sheets mention tungsten...
