I saw this in the Autozone ad and thought I would pass along. Thru 1-9-12 you can get 5 qts of RP and a K&N filter (Filter price up to $20) for a grand total of $44.99. See Here:Deal Maker Page | AutoZone.com I guess you can always use the filter on your other car. Or sell it to get the oil even cheaper. looks like $1.50 off the oil and a free filter.
I would never put Royal Pimple in my car ever, its crap. The April 8, 2009 edition of Lube Report, a weekly email newsletter from Lubes 'N Greases magazine, carries a lead story by editor George Gill titled Truth in Advertising: BP vs. Royal Purple. As it turns out Royal Purple was taken to task by The National Advertising Division of the Council of Better Business Bureaus. The NAD recommended that Royal Purple discontinue making many of their performance claims due to faulty documentation and anecdotal evidence Article from LUBE REPORT
I just looked through the article, but does it have zinc in it? I use it because of the zinc. Most oil doesn't have zinc anymore. I could be wrong.
+1. I just plain hate the way RP does business. They constantly try to bully me into approving RP oils for use in the equipment I design. (large industrial compressors) Yet they have no actual data or compatibility documentation. Only anecdotal information from uncontrolled before and after "tests".
I do not use Royal Purple & the reason I don't is that it costs more than I am willing to pay. For me Mobil 1 0w40 works swell in my MINI & my other cars. If Royal Purple has zinc in it is good for flat tappet engines like your classic Mini. The zinc is not needed as much for cars with hydraulic lifters. The reason zinc has been removed is it kills converter efficiency over time. I'm not sure running synthetic in a classic Mini or any classic is a good idea. Old seal technology sometimes has a hard time keeping synthetic oil in the engine. There are other oils with zdp content & I believe there is an additive you can buy. For me a high quality dino oil with an additive is the way I'd go. Here is one > Oil Additive - Engine Oil Additives - Motor Oil Additive - Eastwood
yes, I do buy it for the zinc. I was told there is zinc in it and I plan to keep using it. I am not a expert on this topic but I did stay at a holiday in.
