C30 Oil Consumption
Hi, I bought a C30 R-Design Lux (petrol) in September, 83k miles. I seem to have an oil problem. So far it's got through 4 litres over the course of 3000 miles. That seems very excessive to me, but I don't know if it's normal or not. The local garage can't find any leaks, and I haven't noticed any smoke, smells or lack of performance. I've done a youtube PCV "glove" test, the glove didn't inflate or get sucked in, it just sort of mildly blew in and out rapidly, so I don't know what that means. It's under extended warranty, but there's a claim limit, so before I start going down that rabbit hole, are there common problems with this model to point to, and are they reasonable to fix?
Any advice much appreciated. |

That level of consumption is absolutely not normal. What engine has it got? The 1.8 petrols are prone to oil consumption problems.

t stat
Just a wild theory, do you know if the car coolant gets up to working temp fairly quickly, as something like a thermostat stuck (open) will cause it to spend most of its time running cooler and possibly will not help with oil consumption (which the petrol C30s do seem to suffer from), try plugging in a cheap obd2 reader and monitor coolant temp on a typical run, it should reach 90c (although the dash gauge doesnt really work like a linear readout).

I'd get the mechanic to do a compression test and pull some of the spark plugs to see what state they're in. If there's fresh oil on them, then that could mean internal issues like valve seals or piston rings.
