Hi,
I have asked about my 2003 1.3 Multijet Mk2b (now has 122,000 mil on the clock) before but not really gotten much of an answer... the story is that in May I changed the oil and filter. No idea what was in there before, but used Fuchs SuperSyn Longlife 5W40. Since then the engine noise when going faster than 50mph - 2200rpm in 5th gear has gotten louder. It's loud to the point where you need to turn the radio up to hear what you're listening to. In my previous question I wondered if this was down to the timing chain, but after taking it to an independent garage that dealt with Fiats, they couldn't find anything wrong with it. Said that the problem with timing chains snapping was down to being starved of oil or wrong kind of oil in the engine. As a fairly new driver I kinda bowed to their experience, especially after they told me that 3 people took it out on a test drive and one of the mechanics accompanied me for a drive, but sadly due to roadworks, we weren't able to get it over about 40mph...
A friend of mine who has a lot more experience with cars and engines than I do said that high mileage engines would be less noisy with thicker oil, I understand that oil does dampen the sound of the engine. However which grade should I go up to?
Really I need a sensible answer - are these engines supposed to be loud at higher speeds or is there something wrong or is it just age/mileage? Certainly it helps in reducing my desire to speed - at 80mph sounds like it's about to explode!
Thanks...
