Which brand is the best quality gasoline?
Is all gasoline formulations made equal? Should you only ride on cheap gasoline and pocket the difference between current gasoline prices? Actually, oil refinery companies are very secretive about the gasoline chemical formula beyond theirs many gasoline blends and what they mean. They go even further not to reveal which oil drilling companies they get their crude oil from.
How gasoline octane rating affect your car?
The gasoline effect on the performance of the car will vary from brand to brand and grade to grade. (And there's even some slight variation within brands, as gas is reformulated both seasonally and geographically.) The best plan is to run the minimum octane recommended in your owner's manual. Extreme conditions such as heavy loads, towing and high summer temperatures may require the next higher grade.
Since the quality of gasoline directly affects engine performance and longevity and fuel economy, along with the environment, it pays to know the facts about different gasoline blends and what they mean.
Check the car manufacturer's octane recommendation in your manual. If in doubt, use an 87 octane gasoline.
Why is octane added to gasoline?
Octane number in the gasoline chemical formula refers to the fuel's ability to resist destructive engine knock or pinging (fuel igniting before the ignition spark).
Costs for a car tune up will pay off themselves in fuel economy and overall better engine performance. Also knowing How to adjust ignition timing to the manufacturer's engine tune up specifications is especially important. Ask PartSource Pro for easy do it yourself engine tune up tips.
As of knocking and octane rating, if your engine knocks, first try a different brand, this may also work for what causes engine pinging. If switching to another brand doesn't solve the engine knock or ping problem, go for high octane gas or add an octane booster during your next gas tank fill-ups.
However, high octane fuel does not provide more power or fuel economy. Paying for octane you don't need is a waste of money.
The quality of the crude oil used to make the fuel has a direct impact on fuel prices. Gasoline prices may be an indicator of the quality of gasoline.
Cheap gasoline frequently contain more undesirable sulfur compounds and may increase combustion chamber carbon deposits. Such compounds contribute to higher exhaust emissions and catalytic converter problems.
What is the bottom line? Don't pay extra for unnecessary octane. If you've modified your engine for higher horsepower, the octane requirement may be higher than the manufacturer's recommendation.
The purpose for a EGR valve. And Why You Should Replace Them At Regular Intervals!
EGR stands for Exhaust Gas Recirculation. The EGR valve re-circulates carbon dioxide from your vehicle's exhaust back through your engine. EGR valve symptoms are as of: experiencing reduced power, detonation (pinging), rough idle, or stalling and hesitation when accelerating.
Inspecting and cleaning EGR valves is easy. First, know how to clean an EGR valve, it will save you the cost of a replacement EGR valve. But if the EGR valve is going bad, performing an EGR valve install is simple. Talk to your Parts Pro at a PartSource near you for more information.
How to clean EGR valve passages? Do-It-Yourself & Save!
A few things before you begin
First, locate EGR valve. Place the vehicle in park. Apply the emergency brake. Start the vehicle. Allow to warm up.
Find the EGR plunger mechanism. The EGR valve plunger meters the exhaust gas recirculation by opening and closing.
Manually rev the engine and check for plunger operation. A plunger stuck open or closed indicates EGR valve problems. Replace the bad EGR valve.

Everything you need for this job can be found at your local PartSource store. Ask a Parts Pro about what you'll need for the job. It's better to have extra spare parts ready for anything that might need to be replaced. The last thing you want to do, is go shopping when you have the car up on the jack.
When taking parts apart, be organized. Keep similar parts together in a safe place where they won't get lost and layout parts in a way that will allow you to put them back in the same order.
Make Safety Your Top Priority
Every vehicle is different. When it comes to maintenance and repairs, always follow the vehicle's owner's manual.
