Looked like a small old Winebago. Not the kind built on the baby Toyota pickup chassis, but I think it was just a single rear axle dually. Best of luck with it, and not "passing yourself" on the road as you see other identical vehicles should be loads of fun. Alec Cordova Taylor, Texas 89 300CE, 150K I did see a black 300CE near my office a couple months back, but other than that, I've only seen two or three in the 3 years I've had mine. ------------------------------ Date: Tue, 10 Dec 2002 12:07:14 -0800 From: john Subject: Re: oil-101 At 10:09 AM 12/10/2002 +0000, FSJ-List-at-yahoogroups.com wrote: >Message: 8 > Date: Mon, 09 Dec 2002 19:58:58 -0800 > From: fsj-at-shaw.ca >Subject: explain x w z oil viscosity >so what do the numbers mean >5 w 40 >20 w 50 ect >the bigger number is the thickness cold, and the small number is the >thickness hot. am i right? The first number is the cold viscosity, the upper number is the hot viscosity. In multigrade oils it has the properties of both the lower and upper number. The W is for "winter". A straight weight oil has a specific temperature range. For example, a straight 30W might be from 35 degrees F to 95 degrees, or something like that. I can't remember the details, it was a long, long time ago in a land far away... (actually four days east of here and about 33 years ago... :) Here's some info on hot weather testing, not sure if it'll help. http://www.wagoneers.com/AMSOIL/Misc-TECH/hot-weather-test_1.jpg http://www.wagoneers.com/AMSOIL/Misc-TECH/hot-weather-test_2.jpg http://www.wagoneers.com/AMSOIL/Misc-TECH/hot-weather-test_3.jpg The way dino oil extends it's viscosity is to have an additive package added. These additive packages can also inhibit rust and oxidation. Problem is they don't hold up. And they don't play well with others. :) So these packages often breakdown in the chemical soup in which they live and that's why your oil needs to be changed. Oil does not wear out, it gets contaminated and dirty and the additive package becomes hostile to it's host. :) That's why you see a lot of government vehicles running around proclaiming they're running "recycled" oil. They simply filter, centrifuge and add a new set of additives. Would I run "recycled oil" in my rig? NO. Why? Because they'll never get all of the corrosives and contaminants out of that oil and excessive wear will result. If you let your dino oil go too long it basically turns to sludge. Oil will suspend dirt and bad stuff in it... that's what it's supposed to do. That's why it changes color. That's why you should use a good filter. :) Most of the synthetic oils add little or no additives because the base stock is far superior. Although this is only true of true synthetics. Mobil 1 is a synthesized hydrocarbon and relies on additive packages to extend it's viscosity range. Redline and AMSOIL are true synthetics. But as far as I know AMSOIL is the only one to offer extended drain intervals of 1 year or 25,000 miles with filter change half way, been doing so since 1973. Redline was a racing oil for years and was initially incompatible with mineral oil. The name "redline" implied extreme service/performance - and what the polyol esther based synthetics provide. Today they use a blend with dibasic acid esther, as do most of the synthetics. The formulation is a well-guarded secret. Redline wasn't designed for prolonged use, just extreme protection, as far as I know they still do not recommend extended drain intervals. With any oil, it's highly recommended not to add additinal additives or "treatments". The engineers that formulated the oil didn't intend for others to be mucking around with their concoction. :) Live long, prosper and change your dino oil faithfully... as for me and my fleet, forgetfulness reigns supreme so I use amsoil in all of 'em and don't worry about it... ;) BTW, my XJ just turned 240,000 miles this week... po had faithfully changed the dino oil. :) Soon as the Kendall that was installed when the rear main was replaced I'll be refilling with amsoil 0w30. john - ------------------------------------------------------------------ http://wagoneers.com/AMSOIL/Filter_INFORMATION/air_filter-1.jpg http://wagoneers.com/AMSOIL/Filter_INFORMATION/air_filter-2.jpg SJ Jeeps: 360/401: TS-23 258: TS-12 retail $21.50 XJ Jeeps: 4.0L/2.5L('87 and up): TS-29 retail $29.95 WJ Jeeps: 4.7L: TS-104 retail $47.50 DieselBenz: typical S1118 or S1680 retail $32.50 or $39.85 http://wagoneers.com/AMSOIL/ order 1-800-956-5695 cust# 283461 Snohomish, WA, where Jeeps don't rust, they mold... - ----------------------------------------------------------------- ------------------------------ Date: Tue, 10 Dec 2002 16:17:53 -0500 (EST) From: Richard Welty Subject: Re[2]: oil-101 On Tue, 10 Dec 2002 12:07:14 -0800 john wrote: > At 10:09 AM 12/10/2002 +0000, FSJ-List-at-yahoogroups.com wrote: > >Message: 8 > > Date: Mon, 09 Dec 2002 19:58:58 -0800 > > From: fsj-at-shaw.ca > >Subject: explain x w z oil viscosity > >so what do the numbers mean > >5 w 40 > >20 w 50 ect > >the bigger number is the thickness cold, and the small number is the > >thickness hot. am i right? > > The first number is the cold viscosity, the upper number is > the hot viscosity.

(actually four days > east of here and about 33 years ago... :) i'm going to amplify this a bit, i have a copy of the Bosch Automotive Handbook nearby and it has some good reference material on oil viscosity ratings. W ratings (5W, 10W, 15W, etc.) are at -18 degrees C non-W ratings are at 100 degrees C a distinction is made between Apparent Viscosity measurements made at very low temps where motor oil behavior is non-newtonian and Kinematic Viscosity measurements made at high temps where behavior is newtonian. a major issue in understanding the ratings is realizing that they map to ranges, e.g. 10W --> Apparent Viscosity between 1250 mPa . s and 2500 mPa . s 15W --> 2500 5000 20W --> 5000 10000 20 --> Kinematic Viscosity between 5.6 mm^2/s and 9.3 mm^2/s 30 --> 9.3 12.5 40 --> 12.5 16.3 50 --> 16.3 21.9 another thing to understand is that all oil gets thinner as it heats up. the difference between multi-viscosity oils and straight grade oils is that the slope of the curve is different; multi-viscosity oils thin at a slower rate. richard - -- Richard Welty rwelty-at-suespammers.org Averill Park Networking rwelty-at-averillpark.net Unix, Linux, IP Network Engineering, Security rwelty-at-krusty-motorsports.com 518-573-7592 ------------------------------ Date: Wed, 11 Dec 2002 15:12:29 -0800 From: john Subject: Re: BMW 524TD I haven't seen or heard anything about them... :) I think that there was someone else interested.
