****** might just us 80W90 or similar, not sure though.
After you run some fuel system cleaner through it, change your plugs... They probably need it anyways.
And as far as fuel system cleaner, i would recomend Sea Foam, you pour part of it through the brake booster or some other main vaccum line while its running (clears some carbon out of the engine, cleans the valves and such... Then ya pour the rest in the gas tank to clean the fuel system, it smokes like a mother while your pouring it in the intake though.
