HI Scotty, you are forgetting that premium gas (usually) does not have ethanol, which is crap for your car, and that 10% ethanol reduces gas mileage and engine performance by up to 30%. Dont bother arguing, I work for one of the biggest oil refinery companies in North America and know this subject well. Its why I always use premium in all cars and everything else with an engine, including mowers, snow blowers and minibikes. I dont care about MPG, I care about the car running better, quicker and having more usable power. It also doesnt get clogged up with corn oil residue, Also, you are forgetting that the cars computer can adjust for premium gas and all you need to do is get a better air filter, like a KN and the car WILL run better and get better mpg, assuming you dont spend more time on the gas pedal because its more fun to drive now.

The cars that I have produce that crackling and pop sound from the heat shield of the catalytic converter, and it can turn into an annoying rattle sound if one of the welds holding it breaks free. Also, when changing out tires, pay attention to the weight of the tire and wheel combo. I put Michelin ATX tires on my daughters Subaru Outback, replacing the Continental AllContactPro tires, keeping the stock wheels. While the tires were the same size, this added 5lbs per tire, increasing them from something like 22lbs to 27lbs. Man, is there ever a reduction in off-the-line acceleration by just adding 5lbs per tire. This reminded me of my kids PineBox Derby racing days, when one trick was to shave the inside of the plastic wheels to cut the rotational weight lag of them.

I would partially disagree with what Scotty has to say about premium high octane fuel. Fuel with a higher octane rating lets your engine control computer advance the timing farther working in combination with other things to make more horsepower. If you die easy yum has to keep the timing retarded to prevent knocking as determined by a knock sensor damn the car will definitely make less horsepower and get worse mileage. In most cases the ECM programming will increase timing until it determines that it sense is knocking and then it will retard the timing until it stops. So in that vein higher octane fuel will generate more horsepower and give better gas mileage than lower octane fuel in modern vehicles.

Changing wheel sizes requires matching the rolling circumferences of the original tires with the new tires. Otherwise your speedometer/odometer will be wrong. The center-to-center spacing (track) of the new wheels/tires must match the originals or the steering will be messed up. Wider tires may scrape the fenders or stuff within the wheelhouses. Many cars have 15 on the base model and 16 or 17 on the fancier grades of the same basic car. These are in most cases interchangeable. You can take the 16s or 17s off and put the base model painted steel wheels on in their place as long as the 16 or 17 wheeled model didnt have larger brakes to take advantage of the larger inside diameter of the 16 or 17 wheels.

I have a grand am 2001 V6. Ive been using regular fuel for the past 15 years. Would you recommend using ethanol free over regular? Your videos kind of contradict each other, because in one video you say that if the fuel youve been using for years in your car works well, then keep using it; but then you praise ethanol free in another video. My car does seem to run better on ethanol free, but if its pointless for me to do so if my car was made to run on regular 10% ethanol fuel, then I should keep using regular? Or would it still be beneficial to use ethanol free once in a while instead of exclusively? I know this video isnt about ethanol free, but I had to ask. Thank you

Ok. I have a pre ignition problem with my 1993 Toyota hilux 22r 4x4. It pings all the time if I run it on 91 ( Australia ) so I run a blend of 95 & 98 if fuel is cheap or straight 95 if modest price, but if really expensive Ill blend 95 & 91 & top it up with 98 after 1/4 tank. Had 3 different mechanics have ago at fixing it. One adjusted the valve lash, & tried tuning it, changed oil, air & fuel filters, new spark plugs & leads, dizzy cap. Dont know if the head has been shaved? Maybe since the age & 350k Klms. Would love to be able to run it on plain 91 as its slow as anyway. Any thoughts? Other than that it runs fine, and runs fine on the blend fuel.

Tire diameter can generally go up or down %3 and you could look at your cars forums to see if there are any benefits or downsides to changing size by a small (very small) margin. For example you could have smaller rims but fatter rubber or larger rims and less rubber (not recommended)In my case I got tires that were %3. 4 wider because my car is notorious for having a low-to-the-ground exhaust system that can drag on speed bumps if your suspension system is less than perfect. Instead of changing out a still decent suspension system, the larger tires give me an extra

I dont use premium gas, but I also dont use the minimum. I bought my car in Indiana, where I grew up, where the minimum octane is 87. I moved to colorado in 2016, where the minimum is 85. I used the 85 for the first little bit of time in the new state. I noticed it was chugging along, so I switched back to the 87. She runs fine with the 87, but I pay 20c more per gallon. haha Whats odd is that the surrounding states have minimum octanes ratings of 87. My manual says to use 87, so i am gonna stick with it.

Hello mister Kilmer may I ask you something? You said in the video that when you converte your car from gasoline to LPG or propane, the engine will last longer. Is this with every brand of car? There are rumors that a conversion can make an engine last quite a bit shorter than you may expect. What are your thoughts on this? However Im concidering to convert my 2000 bmw e39 520i with 250. 000km on the clock. Car and engine are running like a charm. What is your opinion? Greetings from The Netherlands.
