2447.0. "Engine Size and High Mileage " by FORTY2::DAVIES () Mon Sep 04 1995 15:13

I'm a bit of novice when it comes to cars.

I need to replace my current car with some thing more reliable,
which I want to run into the ground. I'm currently doing 25,000-30,000 
miles a year.

The main thing I'm looking for in a replacement is reliability and 
low running/maintenance costs (rather than performance, trimmings etc).

My main concern is engine size. Are larger engine sizes capable of higher
mileage, and if so, why, and  by how much?

I assume 
 o that engines become less reliable because the piston cylinders
   and other moving parts become increasingly worn.
 o the main factor determining engine wear is the numer of engine revolutions
   performed in its lifetime. 
 o thus, a large cylinder size produces more power (per piston cycle), and 
   thus less number of engine revs are required to propel the car at a given 
   speed compared to a smaller engine.

This strikes me a being rather simplistic. What about other aspects
of wear ( engine gaskets, transmission etc) where wear is determined by
to mileage or time? 


Are there any makes of engine (diesal or petrol) which are recommended 
or should be avoided for high mileage.

Are there any makes/models which are recommended or avoided? I'm considering
a Rover or Vauxall Cavalier or Astra?

Any advice is more than welcome.

Thanks

    Hi Ivor,
    
    You really shouldn't go far wromg with either a Vauxhall or a Ford as
    just about any modern car (I'm not counting Ladas etc here) should
    manage 100,000+ miles with ease.
    
    The only thing you might want to give a good deal of consideration is
    the diesel vs petrol question. The basis (as I understand it) is that
    Diesel works out cheaper to run if you are doing a lot of miles but as
    the initial purchase cost of a diesel is higher you have to establish
    the break even point where the increase in mpg pays for the extra
    purchase cost. Another thing to bear in mind is the fact that diesels
    require additional oil changes etc (it all ads up).
    
    Personally if I was about to buy a car f

    Ivor,
    
    I would think that the basic mechanicals of a large engine would indeed
    see less wear than a small engine (when driven the same way), however
    there are some things against larger engines
    
    	- often 'sporty' types, and likely to have been driven hard
    	  (If you are buying secondhand). In any case, if you have a
    	  larger engine you do tend to use the extra power.
    	- often more complicated, with more bits to wear out
    	- often have more expensive parts.
    	- more expensive to insure
    	- more expensive on fuel
    	- harder on tyres, brakes, transmission and suspension (and
          probably use bigger, more expensive ones to deal with it).
    
    These factors might well override any savings.
    
    The general wisdom is that diesel engines are long lived. In fact the
    Peugeot high-mileage warranty allows lots more miles for a diesel
    engine than a petrol engine (Peugeot have been putting diesel engines
    in cars for a long time). Diesels are inherently simpler, and should be
    more reliable. I think you do have to change the oil (and filter) more
    frequently though, and the initial cost of a diesel is quite high.
    
    I would say that if you dont need much performance then get a diesel
    engine, if you need fair performance then get a turbo diesel and if you
    want high-performance then get a petrol engine. Generally a
    higher-powered car is more pleasant to drive (especially over long
    distances), as the engine is not having to work so hard and is quieter.
    If you are worried about the environment with diesel emissions, then I
    think some diesels have a catalytic converter.
    
    I currently drive a turbo-diesel and a small petrol-engine car. The
    diesel if much nicer to drive. It has lovely low-end torque (it can
    easily start up the ramp to the motorway junction in second gear from
    idle without using the accelerator pedal at all. And it runs steadily
    at slow speeds in traffic in gears 1, 2 and 3 with no accelerator as
    well). It is also quieter. Yes it does produce smoke, but only when I
    floor the pedal, which I dont often need to do.

    Yes,
    
    I would go with .2.
    
    I have a Diesel Peugeot with 130,ooo miles on it, no probs.
    
    I also had until recently a 2.0i Carlton with 128,000 miles.
    
    Neither car broke down or required expensive repairs.
    
    I have not found the Carlton to cost much more than yer average 1.3l
    in maintenance costs. Generally, although more sophisticated, it is
    better & more substantially engineered.
    
    Keep changing the (good quality)oil & modern engines should run for very 
    high mileages.

2447.4High Mileage Family !!CHEFS::BETTS_CTue Sep 05 1995 19:4816
    I have two high mileage motors,
    
    Mine, a TDi Discovery has 117,000 miles on it. I do however haev this
    regularly maintained ie: every 6000 miles and at Landrover prices that
    tends to cost a bit, but 'touch wood' its yet to let me down.
    
    The wife has a VW Golf 1.6 with 145,000 miles on it and this receives
    very little in the care and attention department, but still it soldiers
    on, infact it's sailed through both it's last two MOT's. The only major
    let down being a voltage regulator, at first I was on the verge of
    buying a new alternator, but took some friendly advice from a local
    mechanic, changed the regulator and haven't looked back since.
