300 Tdi oil, still unsure !!

I get Carlube Gold Turbo Diesel 15/40 from Morisons, it's cheep and cheerful so I change it, and the filter every 3000 miles or near enough.

Chevron/Texaco Delo 400 Q8 T550 and many others meeting the equally appropriate [for you] mb229.1 or ACEA B4 from any brand.

No point going on because every oil company and blender will have an appropriate oil for your need. Consumer packs may omit much of the specifications off the packs. The easiest appropriate ones you will find are mb229.1, ACEAB4 but you should easily find an oil with API CH-4 but your viscosity choice may be limited, mainly to 15w/30 and 15w/40 unless you go for semi/full synthetic oils which meet even higher standards. The viscosity of CH-4 and E3 oil is limited because it is meant for heavy duty and severe duty use, whether that be in cars or heavy plant. Best places to find oils are motor factors, of which there should be a fair choice in your area, each one typically stocking several brands. I use Fuchs Titan HPE in most petrol and diesel engines because it simplifies my inventory. Any brand which meets equivalent standards should be, as near as is practical, identical in performance, although better oils will also meet and exceed lesser standards, if you see what I mean.

Here is a partial list of major names listing ACEA E3/Mb228.3/ApiCH4 oil. It is about halfway down the page. This is in no way a comprehensive list and it concentrates on Mercedes specs. Mercedes actually tend to set standards that are then adopted by others with their own codes.

G'day John...

I use Shell Rimula X 15w-40 in my '97 Defender TDi300 since new, and I've used it in a Toyota HJ45 for nearly thirty years. It seems an _excellent_ oil and I note that Huw's reference has Mercedes listing this as one of its recommendations. ( interesting site, Huw, Thanks for that!!). The 'rocker boxes' are always very clean and both vehicles run excellently. In fact the old 3.6lt nat. aspirated HJ45 gets close to the same fuel usage as the Defender... both around ( av.)10lts/100kms.... and the HJ45 has several hundred K's ( on this rebuild) !!! The TDi300 runs like a tuned sewing machine !! :)) ........ So I stick with what I've found to be good!! :)) . I change the engine oils in both vehicles every 5000K's.

Somewhere, way back, I read where Rimula X is one of the most "highly detergent" oils, viz. it will hold its 'load' for the filter and up to the next oil change whereas some 'lesser' oils deposit a 'sludge'.

Down here in Oz there is a freecall to Shell where you can discuss this topic with a technical adviser which I found to be an excellent 'from the source' . I guess you have similar in your part of the world, too.

Best to buy it in 20lt drums as the packaging of the plastic 4/5lts adds a lot to the price. I pay around Oz$100 for a 20 lts drum , currently.

Hope this was helpful to your thoughts on the TDi300 engine oil.

.... frodo.

Morris Oils 10w/40 Ring Free is just the job, or 20w/50 Ring Free for higher milage engines. Should be around

The important thing is that it holds a massive load of particles that are actually too small to be trapped in the filter. Lesser oils will let these particles clump together and sink to produce sludge. It does this over an extended period with a high load. It also stays in grade longer under extreme duty in turbo engines while protecting the engine from wear and bore polishing over extended drain intervals and over a long engine life.

It is important to note that the Rimula X you use today is not the same as you used years ago. Oils are continually reformulated. I remember when Rimula X and Myrina oils only met CCMC D5/ACEA E2 which is nothing special today but was state of the art then. Today Rimula X is a mid performance long drain oil where such oils are normal.

I agree. The best place to find drums of oil at a reasonable price is at agricultural tractor dealers, truck dealers and general motor factors.

Thanks again all who posted, I finally found what I'm after in a little factor nearby. Miller XFE which has CH4 spec and the rest. £ 15.99 5liters
