A diesel engine will last as long as a petrol (and longer), if maintained as per the manufacturers recommended schedules.

Buttttttttttttttttttttttttt an important consideration is this : Because of their lower rpm range......typically 4000 rpm versus 6500 rpm......it is much easier to high-revv a diesel than a petrol. Even in the city. If you want your diesel to last long, remember to use the torque and upshift soon. High-revvs = more wear & tear. My Jiju had to rebuild his Benz 220 engine @ 1,70,000 kms. Reason? Predominantly highway drives @ very high revvs. Use the taller gears on the highway. On my recent drive back from Goa, I didn't see the need to go lower than 5th / 6th gear on the empty NH4. The engine was ticking over lazily @ 1800 rpms.

Not true - the extra that you pay when you buy a diesel versus its equivalent petrol will be largely recovered at time of resale.

I would give a damn about the monthly running and would go for a modern diesel any day compared to a petrol car. So that makes it two of us.. :D

Well the RPM vs Engine wear comparison should include the engine temperature and weight. Since diesels have higher compression rates, it will generate more temperature and thus more wear and tear compared to petrol which offsets the RPM advantage. The key is diesel is priced lesser in india and that leads to cost advantage. Now latest technology like CDRI has improved reliability of diesel engines. Talking about NVH, petrols are miles ahead

Diesel engines are built to last. They can handle high compression pressures easily. NO issues there. Diesel engines are much more sturdier than petrol counterparts of same power and cc ratings and they run at lower RPM hence the engine wear is much lower. Diesel also has lubricating properties hence the fuel handling parts
would have lesser wear vis-a-vis petrol counterparts. Diesel cars are better built (Engines/Suspensions) than the petrol counterparts hence is more expensive initially.

There isn't a price differential in Europe, yet diesels are popular. Diesels are inherently more fuel-efficient than petrols, with most giving upto 20 - 25% more FE than their equivalent petrol counterparts.

Agree with you but better built? I think it's not a choice to build them "better". It's a necessity considering that they have higher compression.

but you can still turn up the power without serious modifications .
Can you mod a petrol to get an equivalent level of performance increase with a minimum of engine mods like you can with a diesel using pete's box ?

similarly, petrol engines are detuned to survive indian petrol, but the diesels have no such issues!

Actually i too don't care a damn about the monthly running. In fact the diesel car any day more efficient, less expensive on spares, and are also more environment friendly and are build to last.

If you feel you are paying higher cost on the procurement of the car, its recovered with the additional resale value it demands this means that the saving you do on the running cost is a huge benefit.

Ideally the modern day Diesels serves our better than petrol.

Good point. Diesels have higher thermal efficiency? and give better FE even if both petrol and diesel are priced same. But don't they (both pertol and diesel cars in the UK) run quite a lot when compared with Indian usage? Also is the price of the petrol and diesel car same there in the UK? I think even if diesel cars are slightly more costly, this will be offset with the running.

1. From what I have read in this forum - nopes. Dont know the science behind Pete's box so no clue how it boosts diesel power. Or maybe it is putting some additional stress on the engine but no one's found that out yet. People have been doing that on petrol for ages so most issues are known.

2. So basically if our petrol quality improves we will have access to more powerful petrol engines (and maybe efficient too) without any design mods to them (translating to no increase in price theoritically) but improvement in diesel quality wouldn't give us anything in terms of performance & maybe efficiency?

You mean to say that the resale value of a diesel car is more than that of a petrol version?
I thought it would be same or less, considering how people look at diesel being a higher maintenance car when old.

yes that is true. Generally diesel variants of same car model with similar mileage will have higher resale than their petrol counterparts.
Go to any user car website and you will find this pattern.

Exactly reason we don't get VW Jetta 1.4 TPI.

no ways buddy, a diesel car always boasts of a much better resale value. take the toyota innova for example. other examples are scorpio, fiesta, indica, octavia, etc..
BTW, in terms of driving pleasure, why are we discussing resale values? !!!
