Fuel light how many miles left

” Thanks for answering about wash and wax. Whats a good polish to use and is it necessary for a new car? I think a short video on cosmetic would be neat. When the fuel light comes on in my accord 08 i4 2.4L, how many miles can I drive “safely” before it empties? People keep telling me to use octane-89 (plus) where I feel the fuel rating is octane-87 (regular). Am I wasting my money or is the octane-89 benefitial for the new accord? “

First, any good hard wax with carnauba in it is fine, I use Turtle Wax because I’m cheap. When your low gas light comes on, you have about a gallon and three quarters left in the tank. So multiply that by your miles per gallon and you’ll know. And lastly, you’re wasting your money. You only need low ocatane for a low compression engine, Period. Save up for a Ferrarri and you can put high test in that.
