I have a 3 ltr turbo diesel 160 Fiat motorhome and have always used the motor oil recommended .It has a low viscosity of 5W although it is not only fairly expensive but a bit hard to get except from Fiat dealers . Has anyone ever used anther brand of oil or, one of a higher viscosity rating as it is probably not as cold where we travel as in some other overseas countries. Advice would be welcome.
Modern motors run tight bearing clearances. It's built like that due to pollution (EPA) requirements . A few Visc points higher on the lower number doesn't matter too much . Just take it easy for the first 2 or 3 klrs on cold starts . If oil is too thick it doesn't spread properly over bearing .
Welcome to the forum Bill. Don't forget to try the two ongoing games here - 'Who is This' in the 'I Digress' section and 'Pick this Place' in the 'General' Section - a great source to find new places to visit.
G day Bill we have 2013 BT 50 3.2 turbo diesel that operates with a5w 30 w fully synthetic oil and I have been using THE TOTAL Brand which is great and reasonable at $145 20 liter this oil was recommended and I have been using total in my last three diesel wagons no problems cheers
I am led to believe that the Fiat engine is made in Europe for colder conditions, and they recommend their own expensive, (if it is available in your area?) Selena type engine oil
Main brand oil companies recommend their own full synthetic 5W-30 as they are just following the Fiat recommendation grade
I put in my engine full synthetic 10W-40, as I believe I will never, ever, be in less than minus 10 degrees Celsius temperatures, but hotter than the European temperatures, especially as I travel longer distances
If you look up some reputable oil brands, they will tell you what type of oil to purchase from them, for your vehicle, plus the amount required, (from memory 7 litres for your engine)
