alchresearch Posted August 29, 2012 Share Posted August 29, 2012 If the dealers had a cosy tie in with the oil companies wouldn't they be advocating shorter intervals? I meant that in the owner's manual they always recommend one particular brand of oil. Its in the car manufacturers interest to get as much in after-sales from the customer, particularly in nice expensive diesel particulate filters at upto £1000 a time!

Miztasee Posted August 31, 2012 Author Share Posted August 31, 2012 yeah ive heard about them diesel particulate filters, its been cracked now they have issues with PD engines but vag group have switched to common rail engines now to solve the issue and it seems to have good effect, but i dont envy anyone who has to replace one, morrisons diesel seems to be the biggest killer of them, due to lack of anti foam additive in them, im going to give it 3 years before i goto diesel see how the common rails pan out with the dpf, if the petrol engine doesnt bankrupt me first. i believe its esso oil that vag group recommend as thats what logo's on my oil cap, the manual is so full of garbage ive only read bits on cruise control, and the xds system etc..

alchresearch Posted August 31, 2012 Share Posted August 31, 2012 Its a strange thing. Take the DV4TED and DV6TED diesel engines. Made, I believe, by Ford. In some cars they run perfectly well without a problem, in others like the Peugeot 407 they're extremely picky, and just won't run smoothly on supermarket fuel and have constant anti-pollution faults. I believe Morrisons fuel also has a higher %age of biodiesel in its mix. Link to comment Share on other sites More sharing options...
Obelix Posted August 31, 2012 Share Posted August 31, 2012 Most vehicles with DPF's specify a low ash oil, to stop excessive ash from clogging up the filters. I rather suspect most of the problems occur after people don't use this somewhat expensive oil and just use regular oil which then ends witha blocked filter.

Miztasee Posted August 31, 2012 Author Share Posted August 31, 2012 i only use genuine oils as im one of the few that sticks to main dealers, taking the leon to skeggy tonight so will see its true mpg on a run.... if i can survive its unforgiving ride and road noise.

walkertelecoms Posted September 1, 2012 Share Posted September 1, 2012 Considering how the oil turbo feed pipe can get gummed up, and the strict specification of particular type of semi synthetic oil I'd say the complete opposite. Diesels - particularly cars - are far more complicated than they used to be and they need regular frequent changes to prevent the emissions system from going wrong. Agree with you for the same reasons, I have my Renault Trafic 115 changed SemiS every 5000 miles, along with air filter. The fuel filter is swapped on every 2nd oil change.

If you're going to Skeg, don't fill up tonight as the ESSO station on the main road into Skegness is usually about 5p cheaper a litre than most places in Sheffield Edit: Oh, possibly too late on that one Link to comment Share on other sites More sharing options...

I don't think they need to, judging from the comments on here people are quite able to scare themselves into spending a pile more money without the help of the oil companies.

SHYTOT Posted September 1, 2012 Share Posted September 1, 2012 It's a new car. Presumably it came with all the usual paperwork. - Users Manual, Service Record etc. If there's a space in the Service record for a 500 mile/800km service, it probably needs one. If there is no space, it doesn't. Most cars don't have paper service books any more. The whole thing is done on line. I don't think they need to, judging from the comments on here people are quite able to scare themselves into spending a pile more money without the help of the oil companies. You certainly have a point there. The other thing to consider is the cars on board service computer. It works out service intervals based on time as well as mileage. If you do a low mileage the services will come up at quite low mileages. This is fine for oil changes etc, but if a main service requires plugs to be changed it is worth thinking whether it is really necessary. My car is fitted with Iridium plugs which have a life of 100,000. Because the car does a low mileage the "D" service came due at well under 40K. The dealer mentioned this and didn't change the plugs which cost around £30 each. Not all dealers are so honest. Link to comment Share on other sites More sharing options...
Grandad.Malky Posted September 1, 2012 Share Posted September 1, 2012 FACTS: car only has 480 miles on clock first 3 years worth of servicing is included with the car (are they avoiding one to save costs) also im lucky to get 30mpg atm which is heavy on the pocket I bet you have been talking to some of the old boys, they had cars in the day when you had a sticker in your back window “running in” … you don’t see them anymore do you 30 mpg … you don’t wear lead diving boots do you … every time you put your foot down and you get that adrenaline rush when the turbo kicks in just think of the ££££££££££££££ going down the toilet.
