Use pulp for less ping
Asked by K. Cryer
I drive an '85 Volvo 240 and, now LRP has gone, I'm told I should use ULP with an additive like Valvemaster. Is it necessary?

23 Oct 2003No, the Volvo has an alloy head with valve seat inserts so there's no need to run an additive, but it might ping on regular unleaded. There shouldn't be any problem running it on PULP.
