Short trips don't do any engine any good as they don't get hot enough to burn off the water etc in the engine. 2.4 90 XS

That was how i understood it...but the amount of cars and all these new modern diesels, whos short trips are their life - i wondered if this was still the case.
Looks like it may be so. Mike |

I agree with Grockle - short trips are never going to be particularly good for an engine. I would have thought that a modern engine will electronically vary the mix to compensate (to minimize emissions) but it naturally won't run as efficiently as when it's up to temp.
That said, with modern, cleaner fuel, I don't know whether it makes a material difference to the life of the engine. Maybe change the oil more frequently than the milage would otherwise indicate. One that started out as a 2.4 TDCi 110 XS + New Defender 110 First Edition |

Quite interesting,
In big turbines the life and service cycle is affected by the start - stop cycles and the hours running. regarding the start-stop cycle this is mainly because when the motor start or stop the operational conditions are not equal to the designed ones, producing stress over the materials (i.e. sudden temperature changes when we start or stop, oil flows not in regime, etc). So, the same should happens to our motors. At the same mileage, a car with more start-stop cycles will be more deteriorated.

Does it not say something about service intervals on the back of the service sheet for the TDCI?
Something like repeated journeys under 5 miles and the oil change is 6,000 miles. |

Thise are exactly "severe conditions". I would change the oil more often as at every (cold) start, non-burned diesel goes into the oil sump. As a matter of fact, in our long thin country fleet buses driving long distances change oil every 200k km. Believe it or not. (Scania, Mercedez, etc big diesel engines).

Yep, as the maintenance sheet said for cars used in harsh conditions:
If the car works in ralenti or at less than 16 km/hr for more than 50% of the time, the oil change should be every 500 hrs For frecuent short trips (5 miles or less) with continous start - stops the oil change should be every 10,000 km. This include also driving in dust enviromnents, hot weather (over 35°C), Defenders towing or working in slopes (Looks like almost all of us falls in this category) Also if fuel Sulphur content is between 0.3% to 0.7% the oil must be changed every 10,000 km if the content is over 0,7% change the oil every 5,000 km .

I assume those recommendations are based around using the 'Ford' spec 5w-30 semi-synthetic oil.
If you did a lot of short runs of 5 miles ish (but not really 'severe conditions'), surely a 'long life' fully synthetic oil that exceeds the Ford spec would help? Thinking here like the (very expensive) 5w-30 synthetic oils that VW/Audi specify. Greg Currently: 2013 90 2.2 Puma Base Station Wagon 1991 90 Tdi 2015 Discovery Sport 2.2 |

Hmmm. Looks like an interesting comment from the Castrol Q&A Website:-
'Q. I notice EDGE 5W-30 – can I use this for Ford engines? A. No – this is specific oil for vehicles specifying the VW/Audi specifications and is not suitable for Ford engines which specify a 5W-30 semi synthetic (FRD 913B). For modern Fords, we recommend the use of GTX Magnatec 5W-30 only.' I've checked and the FRD 913B spec they refer to is the same as the WSS-M2C 913B spec that's in the Defender (2007 onwards) handbook. This is especially annoying as I've just bought some Castrol Edge 5W-30 (VW/Audi spec) synthetic oil to top up the wife's A3 diesel, and I assumed it'd be ok to use in a Puma Defender as it's a much higher spec (and much more expensive) oil than the Defender needs. Good job I checked before the 90 needed any! Greg Currently: 2013 90 2.2 Puma Base Station Wagon 1991 90 Tdi 2015 Discovery Sport 2.2 |

This may not be exactly what you are asking but I was interested in how you should drive a modern diesel in order to keep the injectors clean. I got this reply from Shell
Shell fuels contain detergents and additives that help keep injectors and parts of the engine clean. As for driving hard I'm not sure how that could help and would advise talking direct to the manufacturer on this matter. I can tell you however that Shell V Power fuels have 4 times the detergency package of the standard grades. Filling up say 1 in 4 with V Power would certianly help keep the injectors cleaner. |
