And just out of curiosity, what if the difference was not in the number of cylinders, but the displacement - i.e., if a 4cyl., 4.0 liter engine was tested as a 4cyl., 5.0 liter? How would the results be impacted in this scenario?

Say I have a 4 cylinder engine and send in some oil for analysis. It comes back, but upon review I realize they tested it for the 6 cylinder model. They both hold the same 5 quarts. How will this effect the results? My naive logic says that the 6 cylinder engine oil will have more elements in...

This forum is the most informative for its subject matter I've come across, and thanks for the feedback. I got my car with 22 miles on it and kept it below 4,000rpm for about 1,500 miles. I progressively bumped it up 1,000 rpm's per 1,000 miles. I redline thru the gears (7K) about 2 days a...

Just got my very first analysis back for my 2002 WRX. I'm pretty excited, and I really think taking the time to break the engine in properly has paid off: 2002 WRX 32,600m on car 4,888m on oil Subaru filter Mobil1 5W/30 Aluminum 3 Chromium 1 Iron 7 Copper 1 Lead 2 Tin 1 Molybdenum 71 Nickle 0...

Subaru dealers include Krex Graphite Engine Lubricant as part of their 'scheduled maintenance' LOF service. (ironically, they say Krex 'contains no additives') They also use Krex Fuel System & Injector Cleaner. The claims: * Wider range of temperature protection * Prevents 'dry-start' *...

Thanks for the quick responses, folks - this forum is really on top of things! I'll wait and save some dough. But as a green newbie, I have no clue how to go about analyzing oil. Do I throw a rag in an envelope and send it somewhere, or is it more like a home pregnancy test? [I don't mean to...

I have a WRX, and switched to Mobil 1 at the third change (9K miles). I use a graphite additive (Krex), and I still change every 3K miles though, since I often shift around 6K rpms, and even cruise at 3500 (mainly because 40mph is at a bad spot for 4th gear, and I have to drive that speed quite...
