I wonder - would you change the cam belt, tyres, anti freeze and brake fluid at their half life?
Lots of old boys on here do oil changes every year because that's what they used to do 20 years ago and keeps them in their comfort zone I guess. Modern engines and oils are a different kettle of fish altogether and these days you do not even have to check your oil level as you will be informed by warning lights etc., if there is a need to take action. Follow the service manual that came with your vehicle. The people who designed, built and tested the engine will know far more about it's servicing needs than anyone on here. My 2011 Fiat 2.3 engine did not need its first service until it had completed 30,000 miles or reached 2 years whichever came first. Why would you disregard the manufacturers advice ?
Agree with Lenny again (this is getting a bad habit ).Change ours at 2 years, no problem at all with modern semi-synthetic oils on our 3rd Ducato never been a problem the latest one uses fully synthetic oil even better. Long gone are the days of 5 miles after an oil change the oil was as black as soot, with the better oils and better manufacturing tolerances if you dip the oil after a few thousand miles it still looks golden like petrol engines do.
Only 12k. You are not getting out enough Phil.We just had our first service according to Fiat, 2 years or every 30 k miles. It was 2 years and only 12k miles.
We are getting out enough but not always in the MH. USA,Carribean, NZ,OZ, etc.We need to try and put that right. PhilAgree with Lenny again (this is getting a bad habit ).
Don't often look at the dip stick on our 2015 3litre Fiat based Hymer, because we have a display on the dashboard. But did so about 20 months after we got it and when we were approaching 18,000 miles and the oil looked like new, with little or no discolouration. I am sticking to Fiat's recommendations on servicing.
