TDI Question--short trips
Maybe this has been discussed, but if so, I missed it. I have a Jetta TDI
which, between long trips, is often used for short trips, like 2-3 miles. Is this any worse for a TDI than for a gas engine? The reason that it seems like it might be is that part (or most) of what is bad about short trips is that you don't get the engine warmed up to boil moisture, etc. out of the oil. Since a TDI warms up very slowly, this problem would seem to be worse, unless for some reason, a diesel doesn't put as much "volatile substance" in the oil in the first place. Does anyone have informed comments on this topic? TIA for any response. |

Short hops are bad for any car though... we went through batteries and
exhausts quickly with our 1991 Golf... once every 2-3 years. You are right tho, with diesels they don't warm as fast... and they don't get their best fuel economy till warm, you might be better off sticking with a gasoline powered car. The newer diesels are probably better at dealing with short hops tho... and the one good thing with diesels is that they seem to crank over quicker, this might help prolong the life of the starter. Are you thinking of buying a diesel, or do you own one? If you own one... just drive it... when it warms up drive it a little harder, and change the oil twice a year if you're under the kilometers.

I have one. With the amount I drive, I'd probably be better off with a gas engine, but I like going 600-700 per tank of fuel, and I like doing my small part to reduce fuel usage in an incredibly wasteful society. I have changed the oil at about six month intervals as you suggest. That ends up being about 6000 miles of a mix of about 4000 miles of highway driving, but with a lot of short trips thrown in. |

600-700 MILES per tank? That's wya better then I get (but I have an
automatic). I don't really think you're hurting the car... The car should be built to accomodate drivers who don't drive the car very far - you just might be very cold all the time, where as in a gas car you'd have the heater come on faster.

"Rob Guenther" > wrote in message ... > 600-700 MILES per tank? That's wya better then I get (but I have an > automatic). > Mine is, in fact, a manual. I think the EPA ratings are about 8-10 mpg higher for the manual, both city and highway, and from what I hear, there is about that much difference in real world mileage. I average about 44 overall for mixed driving against 36/47 EPA ratings. This is the first car I've had that would come closer to its highway rating then its city rating in real world driving. |

Yah, my friend had a Golf TDI, now has a Pumpe Duese Jetta TDI... both the
manuals... and he drives these cars HARD, still gets close to the highway rating in the city... I do get close to my ratings too... 6L highway and 7L city I beleive are the numbers... I do 5.9-6.3L in the summer and 6.5-7.1L in the winter in mixed driving... I've gotten 5.6L per 100kms on the highway before... In the autumn, no A/C on, no heated seats, windows closed, cruise control on. "KokomoKid" > wrote in message ink.net... > > "Rob Guenther" > wrote in message > ... >> 600-700 MILES per tank?
