daihatsu owner awaiting engine flushing process

This owner waited patiently for his Daihatsu van going thru the engine flushing process and the grounding kit installation....

He actually came earlier with his wife, asked for explanation on the process, said he will consider and went back, however after 20 mins, he came back and said let's do the flush and the grounding kit.... the van required 4 cycles of flushing before it was cleared, and final fill was with Adnoc Special 10W/30 Mineral oil....
so he waited patiently for almost 60 mins, after all was done, he paid and left....

suddenly, after about 20 minutes later, we saw the van coming back into our warehouse compound and all of us was thinking.... "shit, problem with the van....!!!" we were anxious as the wife was in the van with the husband.... then she got down the van and started asking us what we did with the van..... it was so much lighter and smoother and practically was saying positive remarks....

in fact the van is used to ferry school going children and she was amazed that the little one hour restored the smoothness and performance of the 10 years + van.... without modification and repair works and ultimately, at a very affordable cost....
