Some advice please. I have a Chev Trailblazer - diesel engine. I had it serviced in June last year. Service intervals according to the agents is every 15000km or 12 months whichever comes first. I still have at least 7000km to go to reach the 15000km mark. I don't think a service is required just yet.
Your input is valued.
In my view, if the vehicle is still under waranty, yes, if not, no.
In fact, if you do not adhere to the service intervals, in your case the 12 months, you might loose your guarantee. If not, I would agree postponing the service if you have to pay for it yourself. If you use synthetic oil, which will be the case if oil changes is done at 15000 kms, the oil will still be quite good after 7500 kms even if has been in the engine for a year.
If the vehicle is out of warranty I would also just stick to the 15000km service intervals.
That is unless some one can provide info/proof that the oil somehow deteriorate over time even when not in use.
If you do city /short trip driving , I would change the oil and filter as a precaution ...peace of mind and money well spent in my book !!
Leon, Ek is op dieselfde bladsy as jy. Daar word beweer die opbou van suur in die olie kan skadelik wees vir die masjien en daaroor moet dit nie te lank gebruik word nie. Ek is bietjie skepties oor dié "gevaar" en ruil my voertuie se olie as hulle nie onder waarborg is nie, op die voorgeskrewe kilos en nie die maksimum tydperk nie. En ek moet noem dat ons ons voertuie lank ry en dat hulle na baie jare almal (behalwe 'n Peogeot 504 jare gelede) aan die einde van ons besit almal in 'n puik toestand was en nie waarneembaar olie gebruik het nie. Ek dink dit is dus net 'n teoretiese risiko.
Pierre, If you regularly do city driving, you probably commute by car and then very likely your oil chance interval will fall within the twelve month period anyway. But we each are owners of our own vehicles and treat them according to our own convictions, so no criticism from me.
The coolant looses its glycol over time, usually 2 or (long life) 5 yrs. Also the brake fluid is hygroscopic and needs to be changed every 2 yrs. If those things are not included in the next service then wait for 15000Km.
I would just caution in extending the interval too long while waiting fot the distance if a paper oil filter. . Why? Some time ago I saw a loose paper element oil filter falling into about 10 pieces of paper when removed. I would change the filter and oil now if it uses a paper element oil filter. One would not want to risk unfiltered oil just to save on not servicing it at the 12 month period.
Even if out of warranty, for peace of mind, I will service according to the prescribed distance or time.
There will be a reason why the manufacturer prescribes service intervals. They designed and made the car, so surely they should know.
