DPF removal? Better think again!

Feel free to change your Oil and filters once a year....I do it 3 times a year to keep the engine healthy and prevent turbo blockage.
High miles normally is the result of many motorway miles, in that case sure a 2ltr+ oiler is a good choice

You want low end with long legs and medium speeds , then a large oiler or a V6
You want a high speed performance and long legs, then a v6 or v8
You want a town go cart or school run motor, them a small petrol

Depends on main need

My cars: Kia 998cc petrol automatic, great little thing for shopping short trips.
C5x7 Tourer, working car, motorways and large loads, comfy and relaxing 2ltrTD
Activa v6 petrol for a toy and a great GT car
Healey 3000 3ltr Petrol for brutal fun (when I fix it again) and showing off/listen to it

There's nothing wrong with an early C1. I've got one, it drives spot on. It's easy and reasonably quiet on the motorway and will cruise at 90..

I must admit i dont find any of the little cars rough or noisey, they are no long legged Cruiser but below 50mph i would describe all of them as silent and at motorway speeds very quiet if a little excess wind noise to be expected from a budget small car. A far cry from the Nova, AX, Polo days thats for sure.

If it makes you feel better go ahead. But it's probably money wasted.

Modern diesels just don't need the oil changing every 6,000 miles. This is a hangover from IDI engines which were very dirty and mucked up the oil as soon as it looked at it. I have changed the oil every 12,500 miles on both the Xsara and 2003 C5 (and the turbodiesel Montego which preceded them). The Xsara has nearly 250,000 miles under its belt and the C5 about 220,000. I use a fully synthetic 5W30 oil on both. Both get regular long runs down to France and back which obviously helps. I feel that both engines still have plenty of life left in them.

At last - something we agree about.

Probably yes but I got rid of my boy racer urges years ago rallying in the forests and the like. Now I'm more interested in MPG than MPH.

Yeah, been there and done that. Now my back has decreed that it needs a comfortable car. I really don't think I could take being thrown around inside a car again.

Dunno personally about the early C1 - I'm just reporting what I was told.

As far as the new C1 I had then 65mph was quite fast enough on the motorway thank you. I could run over a penny in that and tell you whether it was heads or tails.

100% agree Dean. Even my C1 is perfectly ok on the motorway. Certainly as refined as a 90s Escort!

Disagree totally..... 2003 engines are not "modern".

The days of internal combustion are numbered.
The writing is on the wall.
It'll be around for a while longer.
Hybrids are a temporary gap-stopper, while batteries/charge devices improve, but are no real solution.
(They are also a way for Big Oil to cling on a while longer.)
Hydrogen may or may not happen.

200-mile range with today's batteries is now possible. Read Tesla, Toyota, Renault-Nissan, and plenty more.
The performance of many of today's all-electrics already exceeds anything comparable petrol or diesel can provide.
The principal problem with air-quality is inside cities.
Most vehicle journeys inside cities are below 50 miles a day, easily met by even existing battery technology.
The speed of battery development accelerates all the time.

We love our internal combustion engines - for many, they're good fun, and we enjoy tinkering.
Big Oil loves them too.
So do the engine manufacturers.
But we have to move on, and quickly, for the sake of urban air.
UK is already seriously in breach of International air-quality standards, and UK government doesn't really want to talk about this.

There may be a few more tweaks that can be made to reduce diesel and petrol fuel consumption, and clean up the emissions, but petrol and diesel vehicles are already starting to collapse under their own weight of emission-control gadgets, with fuel consumption actually increasing in many cases.

We'll be using diesel for some decades yet - but not in cars, and not in cities.
Some of us are old enough to remember electric buses - silent, clean and immensely quick.

It's time our cars, taxis, buses and vans acquired these essential properties.

I agree with you Ben. I know I am 45 miles from a dual carriageway and 120 from a motorway, but in my last 107 I went from home to my sister's and home all in one day, a total mileage of 440 steady indicated 80 on motorway and dual, 65 when possible on the single carriageway, 62 mpg for the whole tank and I am 6 feet and fat and was totally comfortable doing it. As good, as powerful, as comfortable as the 1981 astra 1.3gl which was my second car and streets ahead of the 1975 allagro that preceded it. Mind you the allagro couldn't do 400 miles without running repairs!

My modern derv has 12.5k service intervals, if it would stop firing fuel into the sump i may make half that one day, i can dream.

My daughters 2008 astra 1.9cdti has 20k service intervals, never gone more than 10 in her care, last one was 8k and the oil had risen above max so it's in danger of exploding on its own oil/fuel mix. It's probably down to 5 to 6 k now, and use the cheapo oil possible lol

I'm talking about DI as opposed to IDI. In that context the 1989 Montego is modern.

[Stickyfinger]

No it is not.
It is not designed to digest its own crap like a modern engine whatever it's design basics.

Which one is that? Regardless, there's something wrong with it and not something as a mere function of it being diesel.

[daviemck2006]

No it is not.
It is not designed to digest its own crap like a modern engine whatever it's design basics.

It's still better at 5 to 6 k with cheapo oil as long as it meets the spec than 20k with expensive oil. It's done 135000 now, she has had it since 21k.
