  1. Some gas station uses cheap un-refine fuel which create sludges. While others such as chevron and shell uses cleaning agent in they're fuel to keep the engine from carbon build up and sludge build up. I personally use chevron and shell only for all of my vehicles. I stop using Arco after what it did to my Nissan 240sx. It ran like shit to the point where I just ended up giving it to the junkyard because it would not go when stepping on the gas, it was slipping going up the hill.

  2. You will notice the difference in how your car performs when switching between those two types of fuel. If you don't notice any difference when you use premium fuel, then just stick with the regular unleaded. But if you do feel a difference, then it means your car just performed best using the premium fuel. All in all, it just really depends on the vehicle.

  3. If he'd been using conventional oil for a long time and switched to synthetic oil especially on a high mileage vehicle it will just create more problems down the line due to the amount of wear on the engine it already has. By switching to synthetic it will do more harms then good so just stick to conventional oil as it will continue to help lubricate all those worn out parts. You don't want to go from thick oil to thin oil especially on a high mileage vehicle. When the engine is new then yeah its best to switch to synthetic for longevity and less friction.

  4. Nitrogen are only beneficial for when you're on the race track, and you don't want to risk having a tire blow out while racing. That is why all race car uses nitrogen instead of regular air when they're on the race track. Nitrogen is an inert gas that remains the same in all driving condition. They do not expand and contract like regular air. Regular air expands and contracts when it gets hot and cold creating flex which in terms causes a lot of stress on the sidewall eventually you get a tire blow out.

  5. It just really depends on the vehicle. Some engine will perform really good with premium fuel while others will do nothing at all, hence why some just stick to regular fuel.

  6. It just means that his car will run much better with premium otherwise he can use regular unleaded if he don't cared about the extra oomph! If he just use it for everyday commute then regular would be fine. But if he has a lead foot and loves that extra Oomph then he can opt in for the premiun.

  7. I usually put 10 psi lower than what the max psi says due to the varying weather conditions. As the tire heats up, the hot air will increase inside the tire. When it's cold, it will fall back to what you put in. And the only time I put a full tank of fuel is when I go on a long road trip. Otherwise, I just fill it halfway for everyday short trip driving. As for whether you should use premium or regular Unleaded, it really depends on your car. Some perform better with premium unleaded. While other cars will perform fine with just regular unleaded.
