Higher Octane levels in the higher grades of gas. All gas should be unleaded now.
They're usually Regular Unleaded, Mid-Grade Unleaded and Premium Unleaded.
unleaded. The grade is a personal preference. You can start with the low grade, and if it runs fine that will work, sometimes they like mid to high grade and run better, but you can use any as long as it's unleaded. Fill it with each to see if it runs better with higher grade and then make your decision.
No, it's fine. That's basically mid-grade gasoline.
you can but i would recommend using mid grade
if it has been rebuilt regular unleaded,but if it has alot of miles mid grade or high grade
Regular or mid-grade unleaded. You can run supreme if you'd like, but there'd be no benefit to it. There are currently no diesel options for the Explorer.
If you're in North America, it'll be set up so you can run Regular Unleaded. You won't gain anything by using 91/92 octane Premium Unleaded, but I would recommend running mid-grade rather than Regular... it burns more evenly, and is less prone to premature detonation in the cylinder, and you can gain fuel mileage from it.
You can't. You either have low-grade marijuana, mid-grade marijuana, or high-grade marijuana. There is no magical alchemy that can change schwag to skunk. If you want better weed, then you have to find someone who sells better weed.
Most likely, premium, but nothing less than mid-grade, and run premium every few tanks.
Good Ride and Primewell tires are both considered to be mid-grade tire products. Good Ride tires are often placed on new Ford vehicles and are considered to be slightly better than Primewell.
Unleaded gas was first started in the mid 1970's as a way to combat the smog in the larger cities. All vehicles manufactured after 1986 were required to operate completely on unleaded gasoline.
Unleaded fuel was introduced in the mid 1980s, it depends what engine it has, if it needs leaded fuel you will need a new engine
