Standalone turbocharger lubrication
Standalone turbocharger lubrication
(OP)
I'm currently assembling a Mazda rotary 12A based vehicle in the interest of adding FI. These engines don't have an easy place for the turbo drain oil to return to. I'm planning on oiling the turbo with a small, separate standalone lubrication system. I have a small fluid reservoir, a suitable electric pump and a small oil cooler so should be good to go. My question is: Now that I don't HAVE to use standard motor oil for the turbo, would use of any other lubricant be advantageous for this purpose? I'm thinking something with lower viscosity so as to help reduce lag and spool time. I've seen those gentleman who make the hobby jet engines out of old turbos use ATF in apparently successful attempts to reduce the shaft friction. Mods: might I want to move this to the Automotive Lubricant Engineering area? Apologies if that's more appropriate.

I take it your supply pump is providing similar pressure to an engine oil pump.

Automatic transmissions are full of gears(shearing loads) and organic clutch material and I assume that ATF is formulated to meet those needs. The turbo is just a hot metal shaft running in a metal tube, so motor oil sounds pretty good to me.
Be sure to include a breather in the system.
