Yeah, it's good for starting brush fires! Buy Castrol!! I have seen the insides of motors using Quaker State And Pennzoil UUUUUgly They looked like someone dumped coffee grounds into the motors, seen very few make it over 100,000. Then using Castrol the insides looked much cleaner with hardly any sludge or deposits, It's the only kind I ever use. I owned a Nissan with 204,000 and it was still going strong and have several friends that have over 100,000 on theirs and no problems, Also my wife's car has 134,000 on it with no problems!!!
