The recently announced RR Evoque update is fitted with JLRs new 180PS 'Ingenium' diesel engine thy claim offers 68mpg and CO2 emission of 109g/km.

JLR are selling the fact that the new engine requires service intervals of 21,000 miles, saves owners money.

Same oil for 21000 miles...wonder what oil they specify for that prolonged workout?

LR have had shorter intervals than most brands for some time - 20,000 miles is now regarded as normal by manufacturers - Vauxhall went up from 10,000 to 20,000 15 years ago, the Vectra diesel being 30,000 for a while but reduced back down to 20,000.

Post-2013 versions of Hyundai Santa Fe have a 20,000 mile / 2 years interval - although dealers are quite happy to add an additional interim in between.

OP

Is the garage using the correct spec oil. On a modern car it can make a difference.

But on your car with a DPF like yours using the correct oil is critical even just for top ups.

Suggest you look at the receipt which should tell you what oil was used and compare that to the spec in your handbook. Hyundai and Kia specify the same stuff for their diesels so should be 5w30 fully synthetic C3. Its a commonly available spec and not too pricey compared to some.

If its not the correct spec the long term health of the DPF will suffer and compared to using a little oil oil between services that will be a major expense.

.... Which makes it all the more remarkable that manufacturers seem to get away with the oil figures they quote.

They quote them so that it will be next to impossible for owners to claim under warranty. Cars just off the production line will vary in using oil, and from then on their behaviour will diverge further depending on how their new owner/drivers 'run them in'. But I reckon a litre every 1000 miles is a bit too much, whatever has been done to the car.

They're set at a level they don't have to pay dealers for long time consuming checks - if the owner thinks it's using more than a litre/1,000 miles it's simple enough for the dealer to check the oil level, top it up to the full mark, clean any areas which might leak and get the owner to bring it back after 500 miles - clear cut warranty vs non-warranty and dealer gets paid very little for investigation, if anything.

I have found that sometimes just the brand of oil can make a difference to oil consumption as well as the specification can.

Our old Astra was always run on 10w40 GM oil, I then changed to a different brand of 10w40 and it reduced it a little. I now run it on 5w30 GM spec oil and the consumption is even less. Obviously the 5w30 is to the latest GM specs.

These rates are nothing - a Mini Cooper S 1963, 1071cc achieved 135 miles to a pint on road test by Motor. Rather eclipsed by the 1275cc successor tested Sept 64 @ 75 miles per pint of SAE30. Eeek!
