A quick way to save 20 to 40 or more cents per gallon of gas is to stop pumping premium ; and switch to regular grade. But how will you know if the switch is safe or if it will damage the engine in your car?
The key for drivers is to know whether premium gasoline is merely recommended for their car or if it’s required. In today’s automobiles, advances in engine technology mean that even if the owner’s manual recommends premium gasoline ; the car will typically run on regular without issue and won’t damage the engine in any other way. The car’s performance might suffer only slightly: It might be a half-second slower from zero to 60 mph for instance. But the average driver isn’t likely to notice this drop-off.
Drivers used to buy a tank of premium gas every once in a while to clean their engine. Years ago, premium gasoline contained more detergents and additives to stop carbon deposits. But experts say that because of government regulations aimed at cutting emissions, all grades of gas, including those you buy atindependent, low-price stations have plenty of additives to both protect engines and cut pollution.
Edmunds has compiled two lists: “premium recommended” and “premium required” for vehicles ; from the 2011-2016 model years (with some 2017 model-year vehicles). If your vehicle is on the “premium recommended” list, you’re OK to try switching to regular unleaded gasoline. If on the other hand, your car is on the “premium required” list, then you have to run premium fuel. You can confirm the information on these lists by checking your owner’s manual.
