Motorway or backroad

80sDiesel

So i can take 2 routes to work. One all motorway or one all back roads. 
Which is better on my car ?
I am guessing the motorway is great on tires, suspension,brakes,clutch. The only downside is that the revs are higher and i had the oil light come on early before. (Average speed 110-130)
The backroads are harder on tires,suspension,brakes,clutch but my average speed is lower and it doesn't hit the higher revs much. ( average speed 80-100)
Which one is better for the car long term ?

Motorway for certain. There should be no harm to your car at 120km/h even if your revs are a little higher. The motorway is better for your engine since it is at a constant speed. Or at least it's no worse than the backroads.

Topping up your oil is nothing to be concerned about, so long as it doesn't become a frequent event. The amount of oil your engine uses will depend on the engine/age and how well maintained it is. It shouldn't make much difference whether you do motorway or backroad miles.

Motorway is also much safer - you're more likely to be killed or injured in a car accident than pretty much any other activity, using the motorway will greatly decrease the odds of that happening.

Motorway.
As Alan said, revs are not important. The car is designed to be able to handle revs at motorway speeds.

Higher revs don't cause extra wear on engine.
Definitely use motorway.
If you're concerned that at higher speeds your car is using more fuel, then just drive at 90km/h on motorway together with the trucks.

That fires my curiosity.... does your oil light come on routinely or do you maybe leave checking your oil until the warning light comes on?

Motorway for sure.

Yes, nobody's forcing you to drive at the speed limit. There are many other vehicles limited to 80-90 km/h on motorways. Even going down to 100 km/h could make a significant difference in fuel consumption with a 5-speed manual car.

Seems everyone that drives at 90km/h in Ireland does so in the Right lane though :pac:

If you're more comfortable doing 100 in the car on a motorway then do that, there's a passing lane there to be used.

there's plenty doing that speed, count the numbers that pass you when you are at 120 and the numbers you pass.

I passed a lot of people when going to and from Bray on Sunday alright, seems like most were doing 100 on the 120 roads. Never noticed so many cars going under the limit as I did on Sunday. Weather was grand too.

100% motorway. Even for fuel consumption at 120kmph most cars will use less than braking and accelerating on back roads. Drop to 100kmph and keep it constant and you will be at the most fuel efficient and wear and tear efficient you will ever experience

For me it depends on the back road and type of car

Small cars such as 1000 cc will not return such good MPG on motor ways but bigger cars such as 2000cc upwards will benefit from motor ways . Diesel will nearly always benifit from motor ways and larger cars SUV and vans also do better on motorways .

modern cars which use one liter oil per 4000 kilometrs is ok use and very likly for cars north of 100.000kilometrs

One liter oil use per 1000 kilometers is not good sell the car as the oil will gum up the CAT or the particale filter and stop car from getting past the NCT emissions

Drivng from Swords dublin to Ballbriggan with small car i go the back roads on the Sunday for the local flea market there .
Using the Larger car I go the motor way .
The motor way route is several kilometers longer ,
smaller car uses less fuel doing at steady 75 KPH but bigger car uses less fuel at steady 90KPH .

Motorway driving though..... God its depressing!
