“If you have a car that hasn’t been driven for a while, you might be wondering if the gas in the tank is still OK or if it needs to be removed and fresh gas added. Here’s your answer.
Is old gas in the tank bad for your car? The quick answer
In almost every case, old gas is not an issue. Gas that sits does slowly go bad. However, gas that sits, even for a few months can be redeemed by topping off the tank with fresh gas. When the fresh gas mixes with the older gas, the motor will operate properly. John Ibbotson, chief mechanic at Consumer Reports, says that, “The new gas will mix with what’s already in your tank, and any variance in the octane will be adjusted for automatically by your car’s engine computer.” The adjustment will get the engine running back to normal.”

Step 2Next, vacuum the entire mattress surface with the upholstery attachment on your vacuum cleaner. Pay attention to seams and crevices, where dirt, dust, dead skin, and other icky stuff collect; switching to your vacuum’s crevice attachment can help get in deep.Our tests have found that a normal vacuum cleaner provides capable cleaning, but if you’re fastidious, consider investing in the Dyson V6 Mattress Handheld Vacuum, a $250 device designed specifically for the job. In a Consumer Reports at-home mattress test, we cleaned half of a foam Tempur-Pedic mattress with a top-rated canister vacuum and half with the Dyson handheld. The Dyson sucked up 3 grams of material, including dead skin cells that dust mites like to nosh on, compared with the 1 gram that our regular vacuum removed.Step 3Once you’re finished vacuuming, check for stains and spot treat them with an appropriate cleaner. An upholstery cleaner or enzyme-based pet-odor remover can do the job on many bodily fluids. You can also try a simple solution of 1 teaspoon mild dish detergent and 1 cup of warm water.
