Oil That Is Suitable N Fuel Effiecient & Saving On Hyundai Getz 1.3 L (A) ???

As much as all the oil companies want you to buy there products. As long as the grade is correct and meet the auto standards. Also remember that climate can change the weight of oil you should use. Cold weather your weight would go down and warmer weather would make it go up. Most of the time 10w-40 is good enough. The 10 is the weight when the oil is cold and will run as if it was 40 weight when the engine reaches operating temp.

The big question anymore is Synthetic or not. I have gone all synthetic for just the fact that I do not have to change the oil as much. 10000 plus between oil changes compare to the 3000 mile on normal oil.

As for fuel. Most fuels come out of the same pipe line any more. It all has to do with the additives the station or distribution system put in it. Shell my sell there fuel to small companies but they will only stand by the fuel they sell from one of there named retailers. Most troubles with fuel comes from the retailer with water or settlements in the storage tanks. Running there storage tank low all the time will make for more trouble in you tank.

its about detergent, filtration, and octane. The larger the company, usually the better if at a large station. You don’t want to use a station where the fuel may sit for a long time. The busier the station with the biggest name of fuel the better. If you were here in the U.S., shell and Mobile would be the best, but i’m not familiar with all of the company’s you listed. Also, the octane level may make some difference. Though most new cars adjust to whatever octane you use, the higher octane levels usually burn cleaner and more efficient.
