Guys, My car Linea 1.3 is currently at 87k on oddo, 5yrs 4month old. Had done previous regular service at 80k 6month back from FASS Daiwik Fiat, Malappuram. 60k major service done at 52k done from Daiwik. Engine overhaul, half engine and turbo replacement done at 62k from Daiwik itself. Service quality were most of the time below expectations. Last month when I was doing my regular wheel alignment from outside, as there was increased tyre wear due to error in camber and caster values, the operator at the alignment shop gave me the print out and asked me to consult at FASS. I consulted at Daiwik Fiat and after inspection they said after changing lower arm of one side and by loosening something and later pulling and tightening of something of the suspension the problem can be rectified. I asked them again and again if they were sure the problem can be corrected and they were positive on this. Corrections were done, I paid the bill and took delivery. On the very first drive itself I was in doubt. Went to another alignment shop to rule out any bias and the results were shocking. Nothing is changed. I called Daiwik Fiat back and when I questioned them, they were ready to refund the alignment bill !!! Anyway in short that incident was the last nail on the coffin. Next authorized service center is more than 100kms away. So I decided to do my next service at 90k at a local Bosch garage. The head of this garage Mr Appu is an old trustworthy mechanic from our place. When I consulted him, he said he is having all filters and other stuff required for servicing Linea. But still, I ordered diesel filter with sensor, oil filter, air filter and pollen filter from 99rpm. I am confused regarding the oil to be used. I was going for Mobil 1 0w40 fully synthetic oil which is available at 99rpm for 3500 for 4L. There was also Mobil delvac 1 5w40 5L one available for 4000 at 99rpm. When I enquired at their customer support they suggested the second one delvac!! Please help me choose the best oil. Thanking you all in advance.
