DO NOT USE THIS STUFF!!!!!!!!!!
And what's your proof?
Marvel MYSTERY oil????
Most major mfr's recommend that you NOT use additives in engine oil, stating that it could harm components and/or VOID your manufacturers warranty.
That's all the proof I need.
LOL Have you ever had your car serviced at a dealership? There are many additives about such as B&G. But there are also manufacturer labeled additives as well. The major OEMs don't seem to have much of a problem with their dealership service dept's recommending various additives...
It has more to do with testing than with a blanket hatred of all additives. While I agree that properly maintained engines should not need additives as motor oil is chocked full of them, I do believe that MMO is an effective cleaner that may penetrate and dissolve certain deposits as a gentle flush in previously abused engines and I have yet to see someone state that it did any harm to their engine when used properly. I don't think I could ever substitute a quart of oil for a whole OCI, but I believe I've had good luck adding half a quart for the last 300-500 miles of an OCI. The previous oil change I did, I added it to PP 5W-30 for that term, then cut open the filter after the change and found bits of sludge and other debris in the Pureone pleats. Was it the MMO? Or was it the Pennzoil Platinum that also claims cleaning ability? I can't say for certain. But it certainly didn't hurt anything...
