Well I refueled my car from Shell during their Lego car scheme.. I own a civic 2005 and it started giving smoke and starting missing..
All in all stick with Total, best fuel ever.
Coming back to the point, on recommendation I poured in STP and it worked like wonders.. My car was back to its peak performance within minutes and a few full revs..
P.S : I have customized my car and keep it well maintained..
