: Oil Choices in Diesel Engines Dameon 04-23-2004, 12:55 PM This being my first diesel engine, I have some concerns over oil changes... frequency, grade of oil, additives. How different are the diesels to their gas counter parts? Should I change the oil more frequently? Less frequently? Synthetic? Blend? Additives like Marvels? What about an occassional gas additive to "clean things out"? The closest biodiesel reseller is 3 hours away, so I can't use that although I'd really like to. Dameon 06-02-2004, 12:52 PM Interesting. 100+ views and no one has anything to say about oil for diesels? I know I am an "other diesel", but I'd assume it's same-same for general stuff like oil. hotrent1 06-11-2004, 07:36 PM For long life. use whatever high quality you can afford. Change the oil religiously. Personal opionion here: Delvac1 full synthetic oil, amsoil dual bypass filter system. Change both filters 10000 miles and oil whenever you feel most comfortable. Install additional pre-pump fuel filter prferebly 2-micron (there are several available. I went with amsoil/Dahl). Check other sections in this forum and you will find other options for both. I prefer full synthetic oils in all differential, tranny, engines. Good luck Erie Tom 07-01-2004, 11:53 PM Rotella T for me. The big diesels use this one alot. Also a choice of mine would be Delvo by Chevron. These are not synthetic oils. I will change it at 5000 max because trips willbe in that neighborhood before I get home. Heartbeat Hauler 07-30-2004, 02:52 PM Ditto for me on the Rotella T. Every 5000 miles with an A/C Delco filter.

Its smooth for those diesels. My dad is a Diesel Mechanic( Big semi Diesels) and I think they use 15-40W for those too. Will have to double check that. nickleinonen 08-31-2004, 02:23 PM Get 15-40W Oil. Its smooth for those diesels. My dad is a Diesel Mechanic( Big semi Diesels) and I think they use 15-40W for those too. Will have to double check that. almost all OTR trucks use 15w40 engine oil, but when you are running 40+ liters in the sump, syhtnetic becomes expensive salesrep 09-01-2004, 02:01 PM 15 - 40 for sure. I would definitley choose a good fuel additive or run premium. It will pay for itself in mpg alone plus keep build-up at a minimum. Brand of Oil? I would go with valvoline blue or chevron delo if you are going dyno 5-7.5k would be fine. If you choose to save money and time Go Schaeffers or mobil one extend drains to 15k easy. May want to consider oil analysis for the first 2-3 changes. salesrep 09-12-2004, 08:36 AM Please check Vendor Forums for introductory offers. | ||
