Need to start putting , at least 91 octane in there..it manufacturer recommend..I run 93 from Shell. You'll notice the difference , especially doing the miles , your doing on the road...
I know gas is expensive ,right now , but you should be writing it off at ¢43 a mile..the government gives an then they take..get yours back every year , make that car, pay for another. 296 miles @ ¢43 a mile is $127.28. Write off the business expense..just a thought...
