Run an oil analysis after your 5k miles and see what it says. Id be kinda interested in seeing the results.
Ive never used it, but my philosophy has been for a number of years, if you gotta add something to your oil to make it do what it is supposed to do then you're using the wrong oil. But thats me and probably an expected response
I know around here its a fairly popular product. If you are using non-synthetic oil then I could see where it could have some benefits as long as there were no additive compatability issues, but the real story would be told in an oil analysis.
