Mix 1 Quart of M1 VTwin 20-50 Oil with M1 0-40 Oil #4708268

Hello All,

We are using 0-40 M1 Euro oil for some track cars we have (BMW E30, Early 80s Celica, Miata and Volvo). My concern is the oil is possibly too thin for really hot days and I'm worried about Shearing and overall Oil Pressure. The Moly/Zink PPM is 1000/1100.

Should I add a quart of M1 VTwin 20-50 oil to our mix? The Moly/Zink PPM is 1600/1750 which is very close to the M1 Racing Oil Specs and it is of course thicker, which would help us on very hot days. I don't know if the Motorcycle Oil with it's Wet Clutch additives would be bad for our car or would somehow not mix well with the car oil?

Another option is to add a quart of M1 Diesel Oil.

What do you guys think? Thanks for the help!

Ben

Adding only 1 quart should be fine. It is hard to tell if the oil film in critical areas is bottoming out, so a guess for sure. Viscosity does create a thicker oil film in more parts of the engine, so its safe to do.

Probably better to just put in 100% M1 15w50 made for cars, like they recommend for high-performance Corvette track cars. Mixing those 2 you mention should be fine. I think the VTwin oil has an HTHS around 6, so you'd be boosting your overall HTHS from about 3-ish to around 4 with that mixing.

HTHS definition: high temperature, high shear viscosity, which governs how thick hydrodynamic oil films are inside your engine. Also, more of your engine avoids metal-to-metal contact among the bearing surfaces (rings, cams, crank, chain, all) the more hths you have.

Run pure Valvoline VR1 oil and be done with it! M1 is junk these days... use a real race oil instead of a CAFE approved, EPA loving, Toyota Camry oil!

How about a dedicated racing oil instead of trying to make your own? Ed: HEY, WHAT A COINCIDENCE!

You know they make a 10w60, which would be perfect in your hot-rod Tucson Korean car. Only woosies would use less viscosity.

VR1 is not a synthetic oil, I still want extreme temperature protection.

They used to sell Synthetic VR1, but I don't see that stuff for sale anymore frown

I'd still bet it holds up better than that M1 will...

I'm curious as to why the HTHS is relatively weak for such a thick oil? There are oils out there that are 40 weights with roughly that same HTHS. (for instance, Amsoil 0w40 with a viscosity of 14.8 cst at 100c has an HTHS of 3.76) I would think an oil that thick would have an HTHS closer to 4.2 or 4.3.

Why not just use M1 15w-50 to begin with? On the bottle it says it's specifically for racing engines. I'm not a Mobil fan but if you wanted Mobil there is your solution.

Neither is the Mobil 1. - It's JUST SEMI. Not saying bad or good as ELF studies on F1 blends showed a semi blend to work better. Now, Blends of WHAT IDK. I used M1R 4T decade ago to boost HTHS and adds, but it went non-synthetic as it is formulated today.
