Hye guys
Need technical advice from you. I was pouring 10w40 mobil super 2000 in my ride. Once i have to tour islamabad via motorway. I put throtle upto 165 KMH. On return, i found that almost 200 ML was short in dipstick ( as i shown dipstick to oil guy and told me its almost 200 ML) and the reason he told was the 165 KMH speed. Car has odo of 184K Km. Let me tell you mt car has good solid pick and there is no white smoke kinda thing. Well for betterment of my car i flushed my engine and used Mobil 1 5w50. Now i had traveled once again on motorway and again i speed it upto 150kmh this time. Well on return of 1800 km round. It was once again short upto 200 ML. Mechanic told me the same story of over speeding which may cause full functioning of engine and might ended up on consuming a bit oil due to heavy load on ring pistons. Well i am not fully convinced and then drove upto 2500Km now. Now its 300 ML short.
Car has great average. 14-15 in multan city easily and on long route it gives 18 avg at 100 kmh speed. No whote smoke no idling head gaskit is good no heat up.... in short everything is good.
Kindly tell me and diagnose whats gone wrong? Is it over speeding that eats the oil or is it something other?is it engine flush thing?? Kindly help me guys......
