Every vehicle they sell with the “Premium Fuel Recommended” words in the owners manual, they get a kick-back from the oil companies…If it says “Premium Fuel Only”, they get a bigger kick-back…That’s the only way they can sell it…
Remember, the oil companies started selling “Premium Unleaded Fuel” before a single car “required” it…That’s when it only cost .05 cents a gallon more than “Regular Unleaded”. Five octane points?? Most engines can’t tell the difference…
