Lots of you will know my ongoing issues with oil leaks and breather set ups but I was wondering if the car was filled with a thinner oil, like stanadrd modern engine oil instead of 20w50, will this contribute to the oil leaking past the rear crank?

I ask because I know it went for an MOT befor I bought it and they said they had re filled the oil. The oil looks very clean and new.

Modern oils contain too may aggressive additives that 'over clean' older style engines. Use 20/50 to API SE such as Halfords or Comma.

I use the cheapest because it is not in the engine long enough.
