  1. I'm like @dripley and run Delo 400 15w-40 oil and change it between 7500 and 10,000 but that can be over a 2 year time since the truck gets driven between 4500 and 7500 a year.
  2. Then they would slap an oxygen tax on us. One of my Volvos warming up in the morning.
  3. It looks like a condenser used for noise suppression (static and/or whine) that you might hear on AM radio. Volvo used them on their ignition coil, attached to the negative terminal, and on the alternators.
  4. Un hook the mystery switch from the wire between the transmission and the PCM and see what happens. If you have a good lock up clutch in the torque convertor the engine will stall if it is locked up when stopped.
  5. First set of front brake pad replaced at around 43,000 miles; next set at 87,174 (Centrix Posi Quiet). The Centrix were replaced with Bendix Fleet Metlok pads 9/19/19 at 113,147 miles. The truck is used to tow an 8k LB 5th wheel 95% of the time. I wanted a stick shift but my wife had bad knees at the time and couldn't work a clutch.
  6. @kzimmer I changed that hose out for a silicon hose a week later. The picture above is the first one I came across to post here.
  7. Rule out a bad VP44 by doing a "hot wire" test. Do this https://www.bluechipdiesel.com/runningtests or the test below.
  8. You're using an Edge EZ and RV275 like I have. I'm using an adjustable boost controller and have it turned up to 30PSI of boost. I got out of China for $5. Some other members ordered them but I think @Dieselfuture never got his.
  9. A vehicle's GVW is based on it's stopping ability that is why the 8800 GVW brake parts are larger.
  10. There are no bands to adjust in this transmission. There are only clutch packs. This video shows all the part in the transmission.
  11. 'My door looks the same as @Doubletrouble"s and yes, a bear did it. The bears put there claws between the top of the door and the body and pull bending the window frame until the glass brakes. The bear then climbs through the open window and does what ever he wants to do. We had left a banana and a can of nuts no candy in the cab. I never bothered to fix it I have all of my teeth unlike @JAG1 who is slowly losing his marbles.
  12. Some research I did a few years ago on this subject. Posted March 10, 2016 1. From U. S. Department of Energy: Alternative Fuels Data Center: http://www.afdc.energy.gov/fuels/biodiesel_blends.html "Pure biodiesel (B100) contains about 8% less energy per gallon than petroleum diesel. For B20, this translates to a 1% to 2% difference, but most B20 users report no noticeable difference in performance or fuel economy." 2. From U.S. Department of Energy: National Renewable Energy Laboratory: 100,000-Mile Evaluation of Buses Operated on Biodiesel Blend (20): http://www.nrel.gov/docs/fy07osti/40128.pdf "The fuel economy for both petroleum diesel and B20 groups was 4.41 mpg based on in-use fleet data. An approximately 2% reduction in fuel economy for B20 was measured in laboratory emission testing." 3. From Pacific Biodiesel: http://www.biodiesel.com/biodiesel/benefits/ "I want my MPG! Many alternative fuels have difficulty gaining acceptance because they do not provide similar performance to their petroleum counterparts. Pure biodiesel and biodiesel blended with petroleum diesel fuel provide very similar horsepower, torque, and fuel mileage compared to petroleum diesel fuel. In its pure form, typical biodiesel will have an energy content 5%-10% lower than typical petroleum diesel. However it should be noted that petroleum diesel fuel energy content can vary as much as 15% from one supplier to the next. The lower energy content of biodiesel translates into slightly reduced performance when biodiesel is used in 100% form, although users typically report little noticeable change in mileage or performance. When blended with petroleum diesel at B20 levels, there is less than 2% change in fuel energy content, with users typically reporting no noticeable change in mileage or economy. Superior Lubrication for Your Engine The injection system of many diesel engines relies on the fuel to lubricate its parts. The degree to which fuel provides proper lubrication is its lubricity. Low lubricity petroleum diesel fuel can cause premature failure of injection system components and decreased performance. Biodiesel provides excellent lubricity to the fuel injection system. Recently, with the introduction of low sulfur and ultra low sulfur diesel fuel, many of the compounds which previously provided lubricating properties to petrodiesel fuel have been removed. By blending biodiesel in amounts as little as 5%, the lubricity of ultra low sulfur diesel can be dramatically improved, and the life of an engine’s fuel injection system extended" 4. From GAS2: http://gas2.org/2008/04/10/biodiesel-mythbuster-20-twenty-two-biodiesel-myths-dispelled/#myth7 "FACT: Biodiesel contains about 8.5% less energy per gallon than petroleum diesel. For someone using B20, this means about a 1-2% loss in power, torque, and fuel efficiency. To put things into perspective, that’s about a 2 mph difference on the freeway if you were trying to go 55 mph. Millions of miles of onroad tests (aka trucking) have shown that B20 and diesel are practically indistinguishable. Biodiesel has also been used extensively in heavy-machinery, like tractors, loaders, and agricultural equipment, with no noticeable difference. B100 users may notice a slight drop in fuel mileage based on the small difference in energy content, but torque and power are usually comparable. I’ve seen a 1-3 mpg drop in fuel efficiency running B100. As an FYI, biodiesel has the highest BTU (energy) content of any alternative fuel (falling somewhere between diesel #1 and #2). Energy content of various fuels (per gallon, low value of range):" Regular Diesel Fuel = 128,500 BTUs Gasoline = 125,071 BTUs Biodiesel = 118,296 BTUs Ethanol = 76,000 BTUs In conclusion: in real world testing there is no noticeable change in power or fuel usage with fuel blends of B5 (5% bio-95% petroleum) to B20 (20% bio-80% petroleum). B100 (100% biodiesel did show a decrease in performance and fuel economy due to it's lower BTU value. The added benefit of increased fuel lubricity over the ULS fuel is a plus for the consumer in the form of possible lower maintenance/repair costs
