Why does engine oil increase?
Unadjusted oil change intervals If internal leaks occur, oil can come into contact with fuel in the engine’s combustion chamber. The viscosity of the engine oil will also increase, thickening and losing volume. Fail-safe lubrication can no longer be guaranteed, particularly during a cold-start.
What causes the oil level in a car to go up?
One thing I am very worried about is the oil being flooded by diesel from the engine if a DPF recycle is broken. What happens is that you get loads of extra diesel dumped into the engine to burn the filter clean. If you stop whilst the engine is regenerating then the diesel seeps down into the oil down the bores.
Is there an increase in the oil level?
Level was above the upper tip. The increase was not slightly or too much during those cold or room temperature. There was also no oil leakage found. However, when the car was driven and parked for a few hours, the oil level exceeded the upper tip by a bigger length (of course engine was still slightly hot and this is understandable).
What happens when diesel gets into the engine oil?
But if diesel fuel does get into the engine sump is the operating temperature of the oil and within the sump enough to cause the diesel to evaporate or does it mix with the oil and gradually reduce its lubricity and result in more rapid wear of engine components and a gradual apparent rise in the oil level in the sump?
What happens if the oil level rises in a Mazda 5?
Yes, engine oil diluted with diesel is a poor lubricant, premature engine wear will occur and engine life will be reduced. Furthermore, if the oil level was to rise too high oil seals can be damaged and in the worst case scenario oil could be drawn into the intake system which would lead to total engine loss if this wasn’t caught early.

How does a DPF affect your oil level?
But first lets explain what a DPF is and how it can affect your oil level. A DPF is a filter fitted to the exhaust system of the car, as exhaust gasses pass through the DPF filter and soot particulates are trapped inside the honeycomb structure.
