Fair point about the oil usually being too dark for the test strips to work, but my oils are changed while still looking virtually new, so it's probably worth a try.

The Fiat requires Fiat approved oil, the specs probably not that different to other OEM specs, but all similar oils are fairly expensive. There's plenty of controversy surrounding Fiat Twinair oil specs online, some have filled with non-approved specs and reported trouble (which was surmised to have come from the oil actuated intake valves), but I just check the specs on the US Multiair engines and plain old mineral oils are acceptable for them. I ran a Shell 'performance' oil as opposed to the required 'economy' spec at my last change with no issues, I reasoned if it was good enough for a 911 Turbo it should be OK for my Fiat, still cost me around US$70 though (an oil and filter in my TDi cost closer to US$140! - nearly two gallons of DPF spec oil). At the upcoming change I plan to go back to the Fiat spec if I can get a hold of the stuff at all.
