Alan,

Interesting comments and, I'll admit, certainly not an avenue that I had thought of.

Appreciate the input, thank you!

Alan has hit the nail on the head.
There is also another issue with some additives: oil filter.
Is it compatible with the enzimes that hold the paper in your oil filter together or does the paper filter it all out?
Quite a few years ago, As a Dodge diesel owner, I got a warning about using Fram filters. Seems the enzimes in the filter didn't like the diesel fuel mixed with the oil and the paper would come apart and stop up the jets that spray oil in the piston/cyl wall.
Sometimes my customers ask me if I like XXXX added to the oil. When I have no experience with XXXX I ask them if they have ever mixed it with the oil they use and see if it settles out or will stay mixed. Or I ask: is that the stuff I found sticking to the bottom of your oil pan? I always suggest pouring any additive into a partial bottle of oil and mixing before adding it to the engine.
I sell a bottle of Comp with each FT engine and suggest it be mixed with a partial qt. of oil and added just before starting the engine.

Surely nobody would just dump a bottle of additive in by it's self.

Ed---I normally sit on the side lines and dont post, but this one I could not resist. You will be surprised at how many people will put the additive in after the motor has been started and run or running. Instructions mean very little. You should watch these same people put their kids toys together at Christmas.
Also for a further comment. I had used Mobil One for several years as it was really the first synthetic to really be made for the public and it really did work nicely. But as they worked feverishly to remove ZDDP and all other anti scuff materials, we saw problems on the dyno and in customers race engines. So we had to look for alternatives. I tried several but the Joe Gibbs seem to work better than most we had tried and with 400+ across the nose on a stocker cam, it scared me not to look. One day I had an engine on the dyno and Lake Speed Jr(who runs Joe Gibbs Oil) called me and we was talking and I asked what additive I could add to the oil and give me better insurance. His comment back to me and I will never forget it was " are you a F___king chemist and know more than we do. If it needed any thing more to be added to the oil, I would already have done it" Needless to say I have not asked any more questions to him since then. He and his representative came buy a few months back and I surely did not ask any more stupid question. But one thing I can add to the converstion, there are some additive out there that will "blind" a filter and totaly make it ineffective as a filtering agent. I also have seen additives separate out from certain oils. There is know way that you can have an additive and it be compatible with ALL oils. Let the oil people do their job and pay what ever you need to to use their knowledge and spend your time and resources on things you can do something about

I may just be lucky, but for a long time I used Mobile1 and Comp's additive. No sludge, no filter problems. I know others doing it too. I mix 1/2 bottle with 1/2 quart of oil also.

Ed---There is no doubt that many combinations will work and every one to their own. What I am saying is that I do not have the time to develop what my customers need. I must purchase what some else has put their time into and they have far more expertise than I do. There is no doubt that there are MANY combinations that will work. But I know there are several that does not work. I just cannot afford to gamble with my customers on my "magic" potent 109". After they leave here, then they have all the right in the world to make any changes they deem fit. Also if I do have a problem I have an expert to call and run those ideas around in their group. A group thinking, in most cases, will arrive at a better solution than one individual. g,day sirs

Well I guess I chime back in, When I spoke with Mobil about their, the 15-50 M1 (silver/grey top) and the zinc/phos levels. I asked about using an additive, and the guy kinda snapped at me with a "don't use additives"...........so what ever thats worth ??

Lake isn't one to sugar coat his comments , that's for sure . But he's right . How much of what goes into top quality race oils is a pretty closely guarded secret . So without knowing whats in it , theres no way to know what to add . And many , if not most additives fall out of suspension and stay that way . There really isn't anything you can add to a top flight race oil that will improve it , but almost everything you can add will make it perform worse .

He has a very close relationship with Tony Stewart while they were testing. I like them because they continue to develop their product. They are making changes to some of the XP line. I have some coming to me to try on the dyno. Should be good for drag racing. There could be better oils out there but I have neither the time nor money to experiment with it. It works for me,

I use Valvoline Non Synthetic oils such as VR1 and NSL oils. As to Synthetic I have used Royal Purple.

As of late last year, I have been involved in 4-5 circle track engines, which the blocks were filled with Hardblok so my first thing was it has to have an oil cooler. Well, With the oils they were running it was not needed and you would be surprised who's bottles they fill (Some in this thread)
