Diesel engine oil
- I have the Universal Diesel in my Capri 26. What oil have those of you who have the diesel engine used in the engine? What brand and weight of oil? Do you use an additive?I've used Shell Rotella 10w-30 oil specific to diesel engines and various additives to keep the fuel from becoming contaminated. I also drain the fuel tank every two years.Thanks,Pete VargaSatin Sheets #148Lake Granby, CO

- Pete,I also use the Rotella brand, but an SAE 30 weight. (The Universal engine manual recommends either 10W-30 or SAE 30.) I attended a diesel maintenance class this spring and the mechanic recommended the Rotella brand, they had been using it successfully for several years. This sounded like a good endorsement.At the class we also discussed when is the best time to change the oil, Fall or Spring. The recommendation was to change oil in the Fall just prior to pulling out and to run the engine for a few minute with the fresh oil. The idea is to have the fresh oil coating protect the engine during the winter storage. The oil filter should be changed at the same time. I don't use any oil additives.For the fuel, I use an anti-algae additive, it is a West Marine brand. Dirty fuel seems to be the #1 problem with Diesels. So, regular filter maintenance is a must. The recommendation was to change the primary filter at least every two years and secondary filter every year. Some change both filters every year. The secondary filter (the one on the engine) is a 2-micron filter. The general rule is for the primary to be a 10-micron filter. There is also a small fuel filter located on the bottom of the lifting pump. This one is probably worth changing every couple of years.I know some who religiously remove a couple of gallons of diesel from their tank every spring. They remove the fuel sensor on the tank and insert a stiff hose to draw a couple of gallons from the bottom of the tank. The idea is to remove any water or sediment which may have settled during the winter storage. This sounds like a good idea. I did not do it this year, but will likely next year. I'm interested in how you drain your tank. Do you siphon the fuel or is there a drain on the bottom?Mark ShockeyOASIS #296Cincinnati, OH
- Mark:Thanks for the information on what you do and have learned about diesel maintenance. You said that you used 30W oil. The reason I use the 10W-30 is that I keep my boat on Lake Granby in Colorado where, for example, this weekend it was about 35 degrees in the morning. Many spring and fall mornings it is only in the 40's when we go out. It then gets up in the 70's so the multiple viscosity would make sense. No issue in the summer when temps get into the 80's even where we are at 8300 feet of altitude.I too change the oil in the fall for the reasons you mentioned. I do not use additives in the oil and use the same additive you use in the fuel.I siphon out some of the fuel with a stiff hose, pushing it to the bottom of the tank. I do not know if there is a fuel tank drain. If there is, it is probably as hard to get to as getting the batteries in and out.....talk about a chore!Thanks again for the information.
