Took advantage of the cheapness of so called "gas guzzlers" recently bought a nice big 98 BMW 728i, realy like the car but the trouble is it's built for driving and i don't drive much realy, work is only five miles away, so car ends up doing about 60 stop start miles a week, try and take the car for a good M-way/backroad blast at the weekend but that does'nt always happen (would this help anyway ?).
Is this likely to cause problems even if i keep on top of servicing ?, have changed the oil and filter (Mobil1 new life with a genuine filter), intend to get the gearbox serviced in the spring, car has done 160,000 miles, has a bit of timing chain rattle on start up but intend to get that fixed (hydraulic tensioner)

i don't see it causing any problems.. if anything i would be less worried about a car with a huge engine like this as the engine is not working as hard. why do you think the bmw will give trouble? how long have you worked 5 miles away and have you ever had a problem caused by this before?

nah mate won't harm it. Only thing i'd do is change the oil more often than recomended.
Keep an eye on the battery charge as well. As short journeys with the heated electric seats on, lights on, heater on and windscreen wipers chances are she won't be charging.

Just something i read recently (in reference to big jags) about stop start journeys being harmfull (engine constantly in cold start mode, condensation in exhaust not being burned off), work has been five miles away for five years, not had bother in the past but change cars quite a lot (plan to keep the beemer for a while though), would cycle to work but mostly work very long hours, want to get home ASAP after a 15 hour shift, so take the car all the time.

Ah, cheers, will carry on regardless then  A workmate has a 51 plate Merc, lives even closer to work than me (3 miles), thats pretty much all his car does too (and shops at the weekend), he's not worried in anyway. Will just enjoy the car and stop being so paranoid ;D |

Change the oil at least twice a year, more frequently if possible.
If you can do a longer journey once a week or once a fortnight (say 20 miles @ 70 on the motorway) then it'll thank you for it.
Even then, it will wear out sooner simply because most engine wear occurs during the cold start cycle - but we're not talking "it'll die within a year". We're talking "it'll start to wear out at 200,000 miles instead of 300,000", perhaps.

I don't know if it applies to petrol engines as much but istr that diesels used on short journies can suffer because the oil never gets hot enough to 'dry' off the condensate water that gets in it. The water mixes with the combusion by products and creates some sort of acid that adds to engine wear.

wont do it much harm, but as said, keep on top of the oil changes and get it fully up to temp and give it the beans once a week/fortnight.

The advantage with these more modern engines is their warm-up times are much shorter than lumps of old - so short journeys have less of a detrimental effect than they used to - I do my moderns oil 3 times a year - for the cost of it it's not worth taking the chance anyway
