No,just straight sae20 oil,no detergent.
Nothing wrong with that as long as you change it more frequently, and keep an eye on deposits in the crankcase.
Having said that, the days where diesel engine oil was vastly different in additives to petrol engine oil are long gone, and both sorts are pretty close these days.
Interesting that both our Renault vans call for 5W40 Fully Synthetic, and the equivalent Vauxhall/Opel vehicle calls for 5W30.
They are both made on the same production line from the same parts and have identical spec's for the engines.
We use 5W30 Super Synthetic mostly, the newest van is still under warranty and doesn't quite make 18000 miles between services without topping up, so we have to keep a bit og the 'right stuff' around.
Cleaned out the engine tent this morning, swept out the leaves and cobwebs, the flourescent light came on straightaway, just shows how mild it it.
The dry-sump Lister CE asked about getting its head back on again, and I noticed that both injectors were new, not recon. This an ex-navy engine, probably a generator, and it has dual oil pumps for external oil tank. This had a full overheaul before we got it, but for some reason it had two block studs short....
The Lister CD generator is buried under a pile of stuff, but looks OK, the Diter ditto, and the bottom end of a Lister 3/1 was visible, this one caught fire and had an extinguisher emptied into the inlet to stop it.
