royal purple
Im looking into buying a used 97' baja boss 232 with a built 502. The original owner and builder of the engine has used royal purple racing oil since break in. It now has 100 hrs on the engine. Does anyone have an input on using this oil? I have always used mobil 1 in my truck, but do not have any experience with this stuff. I have heard of race cars using it but not boats, is it good stuff and is it worth the money? Will it hurt anything switching to mobil 1 or should I continue to use what the engine has always used. I have always been confused when it comes to oil brands and conv. vs. syn., EVERYONE has a different opinion. Please help! thanks, Derrick

I have run Royal Purple since 1997 I love it. Supposed to be great for bearing surfaces.

Royal purple is better than Mobil 1 in my opinion. But dont use the racing oil. It doesn't have the corrosion and water inhibiting additives the regular SAE oil does.
I would use the regular 15-40 Royal Purple. I've talked to engineers at RP and that's what they told me.

I'd have to agree with Dave F.
I ran RP Racing 50 all year last year and although it seemed to perform great I did get some rusting on the rockers. If you can afford to change it often it would be great.
This year I have switched to Amsoil 15-40 Diesel / Marine in my blown 540. This was recommended strongly by Amsoil tech.
No results as of yet.

Nordic be sure you don't have condensation in the valve covers this is a common problem ,may need a pcv valve
50 weight oils ??you must have some wide bearing clerances ?? that determines the weight of the oil ..
I relly like the oil your running now it will do well ,but nothing will work if you have condensation ,good luck
