Hey TXGRN, I hope your only able to find one with credentials. If you find two or more you'll be so confused by the time their done talking you'll wish you'd simply asked us MORONS on here. I don't have any credentials as a lubrication engineer and since I work on equipment for a living, I've have asked many questions concerning lubrication over the years myself. I've talked to guys that were supposed to be lubrication engineers with CAT as well as with Komatsu and always came away from the encounters with more questions than I went in with, and some they were unable to answer. Through CAT, for example, I couldn't even get an answer concerning the oil capacity of a partucular engine. Now they designed it, surely they ought to know how much oil the pan held...NOT...I had to measure how far the crank throws protruded into the oil pan and filled to just below that level to prevent the throws from hitting the oil. The engines been running for nearly two years now so I must have figured somethig right. Through Komatsu I got told that engine oil would work in the hydraulics, then that it wouldn't. Then I was told that although the manual called for/allowed use of a multigrade oil in the hydraulics that it this specification was an oversite from the manual being printed in English. The only multigrade oils available in the US are detergant motor oils and I shouldn't use them in the hydraulics.... In the end I decided to take the MORON route and rely on past experiences and used a single weight hydraulic oil. Funny thing when the customer change to the oil recommended in the manual, a 15w40 detergent motor oil, he started having problems that lead to a pump failure. I got him to change oils and there have been no more lubricant related problems with the machines hydraulics. All around this MORONS recommendation is to go with one of Lubrication Engineers oils. We recently tore down a 3306 CAT with 12 years of daily, production use since it's last overhaul. It went down because of electrolosis eating a hole in the liner by the way, nothing oil related. After twelve years of daily use the crank came back from the machine shop with a tag saying standard on both the mains and the rods. Dad's been in this business for over 30 years and said he has never had this happen. Got another customer turned onto their products. With their oil the temps on his air compressors dropped 15 degrees and he's now getting over a year out of the turbos with their engine oil instead of 9 or so months like he was getting with Rotella. So, not trying to be a smart a--, but you can find your engineer if you want, in fact here is a good site to start looking, but in the end us MORONS and our real world experience will beat an engineers degree any day of the week. By the way there is a printed magazine put out by the operators of the Mach. Lube site. Some of the articles can get a little technical some time but you can still also learn alot from them. Good luck on your quest.....Wayne
