Good day
Is ATF suitable for use as damping oil in SU carburetors?
Thanks
Greig

    ATF is perfect and is in fact what Volvo says to use. People that use thicker oil are masking a problem with needle selection or other problems like incorrect ignition curve or retarded cam timing.

    Original SU oil is approximately 20 wt.

    Most ATF is 10 wt.

    So I mix equal parts of 30 wt engine oil and ATF to achieve approximately 20 wt.
