Try Velocity in your car, particularly if you have been experiencing knocking. 

If the knocking disappears and acceleration improves (don't just imagine that you're going quicker), then by all means continue using it.  It may cost about P25 more per full tank of 50 liters, but if it gives better performance and contributes to longer engine life, it will be worth it.

If you don't experience any improvement at all, or performance suffers, then you're better off using unleaded gasoline.

Take note that you might have to load several full tanks of Velocity to perceive any benefit.  You must run the car on the new fuel for about a month or about 2,000 km. before you decide if there's any improvement.

Environmental Concerns

If you're driving a 1980 or newer model, take note that leaded gasoline will not improve the performance of your car!  Lead will permanently damage your car's catalytic converter (if present), leading to more pollutants.  The lead will in addition contaminate the air and, among other bad effects, cause reduced intelligence in kids.  Cars requiring lead because of weaker engine materials can also be run on unleaded-just load leaded gasoline every fourth tank to ensure longer engine life.  So if your car doesn't need it, never use leaded gasoline! 

Shell Velocity is unleaded.  Like all Shell gasoline variants sold here, it also does not contain the octane booster called Methyl Tertiary Butyl Ether (MTBE), which has already been banned in the U.S.

MOTION Magazine Survey Results

We also asked our readers about their experiences with using Shell Velocity, and here's a tabulation of our results.  We will update this chart when more readers write in.
