[DOOZIE DAISY]

I used around a litre of 10/40 repco synthetic in only 4-5000km,my motors only done 104000km so it shouldn't burn oil,it was as thin as water when I drained it and had no film strength at all.
I have shell hx7 10/40 semi in it now,the mineral oil was rubbish(only kept it in for one drive),ill see how much it burns over 5000km to compare.
From a back to back drive comparison of the two oils shell recommend the amount of hp lost using mineral oil is way too noticeable,had to try it though.
10/40 Full synthetic has the least resistance,seems to make the most hp and burns the most in my experience with my motor.
If mine only used a couple hundred ml over 5000km or even close to 500ml id be happy,mine used to blow visible smoke when pushed hard!
I might have to try another 5 oils and spend a couple hundred testing oils but once I find a good one it makes it worth it.
