Anyone have a P30 out there? I just got a 1995 P30 Step Van. I'm converting to an ice cream truck. The truck is powered by a 350 Chevy engine. The truck has 140,000 on it.
I read posts here about using oil and decided that my first oil change would be a Castrol GTX High Mileage 5/30 which I did. I'd like to move to synthetic, but I've read about potential leaky seals with the 350 Chevy engine. The truck is new to me. I just installed new spark plugs. Absolutely no oil around the plugs. Does this necessarily mean that seals are good or only the rings? Is it worth the trouble to convert to synthetic? I do my own oil changes on my vehicles, my other being a sedan. I like that I can find synthetic oil with filter for $23-25 and not change oil for 6,000 miles vs 3,000 with conventional oil. Keep in mind this vehicle, as an ice cream truck, will idle a lot or crawl through neighborhoods.
Opinions, please.
