I also found that 15-50 M1 1 gal was off the shelves in all 3 walmarts around here. Only quarts. How's 10-40 M1 ? They still have it in gal's

Do your homework on oils, you'll find by far the most superior and highest grade of oil for marine use is SWEPCO oils. Have done alot of research as well as talked to several engine builders who now swear by it. Call Sepco and compare their data and oil analysis tests with all other, I have several friends who swore by royal purple who have now changed over and have experienced prolonged friction protection, higher WOT speeds, The oil is as good with 25 hours as it is brand new. Do some research and you'll never use anything else. Wiggler

Lube base stocks (of petroleum origin) continue to constitute a major part of today's lubricant. These are complex mixtures of paraffinic, aromatics and naphthenic hydrocarbon type molecules, ranging in carbon number from 14 to 40+.

Different processing configurations involving replacement of dearomatisation, dewaxing and hydrofinishing steps have been developed. Hydrocracking / hydroisomerisation enabled the refineries to produce High Viscosity Index (designated as VHVI or X-HVI) paraffinic base stocks / oils that are comparable in performance to synthetic base fluids. Paraffinic base stocks are preferentially used to formulate most of the world's automotive and industrial lubricants, including engine oils, transmission fluids and gear oils, due to their better oxidation stability, higher viscosity index and lower volatility relative to comparable viscosity grade naphthenic base oils.

They are "paraffinic base stock oils" and are considered group III bases and not PAO's or esters. Supposedly, though....American Airlines uses them in their jets..

I would like to see what additives it has..it's an $8.00/qt oil I believe. Why use it over a PAO or ester?

This compnay makes mostly industrial products and is looking at expanding?

We need data and some UAO's of virgin oil.

Not sure.

They are shuffling the line up... You should see the 15w50 back on the shelves soon.

Also if you want. I can hook you up with an ExxonMobil distributor in your area. Sometimes we can beat the deals that are at Walmart. I think a few OSOers on here can attest to that. PM me and I can get you a list of where you are at. If you are in Indiana, we can try and take care of you.

Craig...what is your scoop on Swepco?

Been around a long time and have never heard of them?!?!

Wait, I am only 24... I asked my old man. He worked for Mobil b/f he purchased the business. He's been around for 30 plus years with GPI and Mobil. Never heard of them either.

Most nobody on Bob's site knows about this product that was only available commercially and now offered for automotive use. I don't know a thing about it...I like to know first...how much ZDDP? What detergents? etc...

Maybe sticking with a tried and true product is for you... and you know what they are by now......maybe you like to try new things...up to ya 'all

Craig is one of the good guys on the board.
His price on V-Twin is excellent and he is a
trustworthy individual.

Great to hear ! ... I guess this change will be M1 10-40 ...
