Changing the engine air filter, oil changes and transmission checkups can help your vehicle run more efficiently and avoid major expenses in the future. Following a vehicle manufacturer's motor oil recommendation can improve gasoline mileage by one to two per cent*. Keeping your engine properly tuned can improve gas mileage by an average of four per cent*.
2.) All gasolines are the same:
Gasoline choice plays a vital role in the cleanliness and performance of an engine. Audi, BMW, Honda and Volkswagen believe that high-quality gasolines that are Top Tier-certified will help keep engines cleaner than gasolines containing only the lowest additive concentration (LAC) set by government standards. For example, Shell nitrogen enriched gasolines are Top Tier-certified and can help protect your engine against gunk and even help clean the gunk left behind from lower-quality gasolines, which can build up in as little as 80 kilometers.
3.) Octane levels in fuel don't really make a difference:
If you use a lower octane fuel in an engine designed to use higher octane, engine knocking may occur, causing the car to shudder and lose performance.
4.) A higher octane level indicates the very best fuel for my vehicle:
It's important to remember that "premium grade" only references octane level, and doesn't always equal “premium quality”. Using a high-quality premium gasoline, like Shell V-Power gasoline, can provide benefits that go beyond octane. Shell V-Power gasoline contains a nitrogen enriched cleaning system with five times the amount of cleaning agents required by Canadian government standards, helping your vehicle achieve optimum performance.
