bro the yellow cng is mineral...and in mineral oils u have 2b really on time 2 make sure oil has been changed coz once it passes its life the oil breaks down thus forming sludge...
yar bro usually oils keh backside par likhawa hota hai in the details of the oil if its mineral,semi or fully synthetic!
n yeh 1 thing for all of u out there reading this THIS IS TOTALLY A MYTH THT ONCE U SHIFT 2 FULLY SYNTHETIC U CANT SHIFT BACK 2 SEMI OR MINERAL!U CAN!!!!this myth was originally generated when fully synthetics were newly launched n they had issues of having the rong ratios of detergents in em!with time they sorted this issue out n made it perfect so now its no problem shiftin to n fro!
haan i wud recommend gng for it as ur ride aint tht old!ulta flushing it will refresh ur engine it will clean all internals tht hav been flooded with sludge...coz eventually engine sludge thus cause damage doesnt matter bmw ho ya mehran coz sludge is deadly for all engines thts y a few oils such as mobil1,liqui moly,zic xq etc hav been porsche,bmw,MB,vw approved coz it passes their tests n r healthy for the engine knowing the engine oil wont give up easily n it has the power 2 protect n clean while lubricating well!
