[DML] Re: Volvo PRV Oil Weight Spec (10W30)





Original Volvo PRV oil spec was 10W40. They recommended such for a
decade or so.

In late 1984 Volvo issued a Technical Service Bulletin making 10W30
the new recommended oil spec, retroactive to the beginning of PRV usage:

"For gasoline engines from model year 1985, the SAE 10W40 has been
deleted from the oil specification chart. Compared to other
viscosities, approved by Volvo, the SAE 10W40 could produce more
deposits in the engine.

The new specification is also recommended for all earlier models."

TSB #21112: Engine [B28F] - Excessive Camshaft/Rocker Arm Wear

40 weight was gumming up oil passages in the rocker arms (imfamous
"camshaft problem", endemic to B27 *AND* B28).
