My engine burns oil, should I use a thicker one?

It depends on the engine, what sort of use it gets, how much oil is being used and type of oil being used.

Certain engines really prefer a specific grade of oil to operate optimally, others aren't so fussy. It's best to ask us if you aren't sure if your car can use a range of different viscosity oils.

Most car manufacturers consider it acceptable for an engine to burn a litre of oil every 1000 miles or in some cases, 1000km. While topping up the oil at that frequency may be annoying and possibly expensive, there is generally nothing to worry about.

Using a full synthetic oil may help to reduce oil consumption if a mineral or semi-synthetic oil is being used. Mineral based oils consist of a mix of different sized molecules and the smaller ones can evaporate and then burn relatively easily, increasing the rate of oil consumption. The molecules in synthetic oils are uniform, so they are less likely to evaporate and burn
