Re: Very interesting info about Royal Purple The fellow who first turned me on to RP was an additive formulation engineer for Texaco. He told me the TBN for this oil was 11 . I too could not find the specs on their website but I took his unbiased opinion at face value and have been using it ever since. He was the one who bought my 94 Viper (the 1 before the 98) and guess what he puts in that?? Mobil 1 Delvac. That's right! A diesel oil in a Viper. His opinion is that you get a much better additive package in a diesel oil than in a regular motor oil. He has converted many Viper owners to use of Delvac

Re: Very interesting info about Royal Purple A TBN of 11 is very impressive! I guess my sources were wrong about the detergent package on that oil. Like I said though, I'd still be careful because of it's other properties.
I do know about the Delvac oil, it's a little secret oil that nobody knows much about, but it's extremely impressive. It's Mobil's best oil. It's hard to find though, and very very expensive. Most people get it at truck stops, but I have seen it at Walmart up here. It's $36 CDN for a 4 quart jug though, compared to $25 for a 5 quart jug of the regular Mobil 1.

Re: Very interesting info about Royal Purple I just ordered a new oil that I want to try by AMSOIL It is a 15W40 diesel and marine oil
Check out the specs.
SERVICE LIFE
Diesel engines, fleet vehicle engines and industrial engines: drain oil at intervals up to two times longer than recommended by the engine manufacturer or at six month intervals. Extended drain intervals may be used if they are supported by the findings of used oil analysis.
Personal car and light-truck non-turbocharged gasoline engines and marine craft gasoline engines: drain oil at intervals up to three times longer than those recommended by the engine manufacturer, or one year, whichever comes first.
Non-commercial, turbocharged passenger car gasoline engines: drain oil at intervals up to two times longer than those recommended by the engine manufacturer, or six months, whichever comes first.
High-performance or racing engines: drain oil at intervals determined by the findings of a used oil analysis program.
Motorcycle engines and small four-cycle gasoline engines: use engine manufacturer's oil drain recommendations

Re: Very interesting info about Royal Purple "I've been doing a ton of research into oils lately"
"I have always been told by a lot of different people that their race oils contain a low amount of detergents, so finding out the TBN of that oil will help me determine if that info is false or not"
"guess my sources were wrong"
So much for all your research. Sounds like it's BS from typical sit on your *** at home oil experts. Since you didn't know RP's TBN value, I doubt you know much about any other of its "properties" to be a credible authority. You should stick to being a digital image retoucher.

Re: Very interesting info about Royal Purple Just because I didn't know RPs TBN doesn't mean I haven't been doing a lot of research. Forgive me for not knowing every friggen number on every oil ever made buddy! I've probably forgotten more about oil than you know, so just keep your mouth shut. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

Re: Very interesting info about Royal Purple So what the hell is your point? Because I didn't know RP's TBN that means I don't know anything about oil? Get real. Whatever.

Re: Very interesting info about Royal Purple I,for one, thank Patman for bringing up this subject on "oils" .I use Valoline Syntec 10w-30w,but open to switching to a better "street" oil for my 11 sec. ride.

Re: Very interesting info about Royal Purple My message is a contribution as it points out how someone is proven not to be as well informed as he would lead us to believe, and this posting misleading information.

Re: Very interesting info about Royal Purple Anyone who brings "TBN", "additive package" and "anti-shear" to the conversation has a pretty good idea what they are talking about.

Re: Very interesting info about Royal Purple It has a purplish tint but is dark and looks like used oil when new! I have used #41 for 3000 mile intervals with great results but I am anxious to try the AMSOIL 15W40 I mentioned. It has great specs.

Re: Very interesting info about Royal Purple I never claimed to be an expert and I don't shoot my mouth off on a topic in which I'm not knowledgeable. Your own admissions as I pointed to in my first message in this post demonstrates that neither you or your sources are well informed.

Dirty oil will dyno less than clean oil, so it's easy to show a gain just by changing oil.
The real test would be to dyno new fresh Mobile 1 5w-30, drain it pour in RP and dyno again. Then 3000 miles later dyno the RP again and see if it showed the same gains at 3000 miles as it did at 0 miles.
