I wonder if a diesel oil is appropriate for this application, or if you folks think something else might be better for cleanliness or wear? Open to any opinions, suggestions, pertinent info, etc. If I could coax it to 150k or beyond without major work to the engine, I'd be a happy camper.įirst oil change I did when I bought it was to put in generic (Blains Farm and Fleet brand, maybe Citgo or Mystik?) 5w-40 synthetic CJ-4 rated diesel oil. I'm hoping for some good luck with mine, and I figure it starts with good maintenance. These motors typically don't die from lube related issues or wear- rather they puke head gaskets at will, cylinder liners come loose, and the blocks like to warp and do crazy things at the sign of even SLIGHT overheating. I'd like to begin a strict 3-5k OCI regimen, hopefully to begin cleaning out the crud, and also looking for decent protection. Could be a by-product of poor maintenance, engine design, perhaps a combination of both. Looking into the oil filler cap, it definitely has it's share of caked on deposits, not quite what I'd call sludge, but not clean either.

Not much has changed with the engine, other than modern fuel metering and emissions controls. It's a dinosaur of an engine, an old 16 valve pushrod, flat tappet design based on the 1950's aluminum Buick 215 V8. Vehicle has 100k and doesn't appear to burn any noticeable amount. As the title suggests, I'm looking for oil recommendations for a 4.0L V8 in a 2000 Land Rover Discovery II.
