Today did a meter top on Suzuki Bolan. It was 1993 model and engine rebuilt once (on petrol, it has no CNG).
It's only 120 kph and I've driven other cars faster than this, but it is very difficult to drive most cars to meter top. I'm happy I did this. Please eat 2 gulab jamun from my side.
Other thing, car is very old and drive more than 300k km, so temperature and fuel gauge sometimes work and sometimes not.
EDIT: Did it on KTHH (Karachi-Thatta-Hyderabad Highway), in the section b/w link road intersection and Sassui Tollbooth.
