Exclusive Motors Often Asked About Premium vs. Regular Gas

Placentia car owners often ask the question: “Will using premium gas make my car run better?” The answer is simple. But first, let’s talk about what exactly premium gasoline is.

Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Placentia, California also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.

Engines require different octane ratings because of design differences. For example, turbocharged engines usually require premium gas.

There’s a sticker on your gas tank filler lid that tells you the minimum octane rating your car maker recommends.

For help identifying the type of gasoline your engine needs, come by Exclusive Motors in Placentia:

Placentia auto owners should read their owner’s manuals carefully to see if it’s acceptable to use lower grades. With some cars in Placentia, California it is; the engine control computer can adapt. Placentia car owners will lose some performance, but won’t do damage. With other engines, using a lower grade of fuel could result in serious and costly damage; so you don’t want to save a couple of bucks at the pump only to pay it out a hundred fold at your Placentia repair shop.

Your car will run best on the type of gas recommended by the manufacturer.

Today’s computer controlled vehicles are optimized to run well on the recommended grade of fuel. Using a higher grade than is recommended will not give Placentia drivers any additional performance or better fuel economy.

Regulations require detergents for all grades of gasoline, so your engine will have the same protection, regardless of the grade of fuel you use. If you do hear some knocking or pinging from your engine, take it seriously and get your Mercedes – Lexus into Exclusive Motors. It may be a sign that you need a tune-up or some other repair.

In times of pricey gas prices, most Placentia drivers are conscious of making their fuel dollar go further as we drive around California. Be sure to use the right gas for your car. Keep your tires properly inflated and your vehicle well maintained and you will get the best gas mileage possible.

Maintenance for High Mileage Vehicles In Placentia California

Many people in Placentia are keeping their vehicles longer. The economy has influenced that, but the fact that modern Mercedes – Lexuss are more durable and reliable means that owning a high mileage vehicle doesn’t have to be a painful experience.

Local car owners in Placentia with over 100,000 miles on their vehicles often ask which service intervals they should follow. Let’s start with the special needs of the older vehicle…

The reality is that time and mileage will take its toll. The engine and transmission will have more sludge. The fuel, steering and brake systems will have gum and varnish built up. There’ll be more dirt and contaminants in the fuel tank. Corrosion and deposits in the cooling system. And seals and gaskets will start to dry out.

All of this, plus normal wear and tear, means that the engine might not be as strong as new, so it just has to work harder to get the job done.

So we need to compensate. Consider high-mileage formulations for oil changes, transmission service, etc. These special formulations contain additives that condition the seals and gaskets to prevent leaks. They also have more detergents to clean sludge and other deposits. They cost a bit more, but they’re worth it.

In general, if an auto service was recommended every 15,000 miles when the car was new, you should continue to get the service done every 15,000 miles.

Talk with your Placentia service advisor at Exclusive Motors about the condition of your engine. See if he thinks you should adjust your auto service intervals for oil changes or other auto maintenance to account for the older engine working harder.

Expect the oil filter to get dirty faster. Same goes for the fuel filter. And some leaks are to be expected so you need to keep a closer eye on fluid levels.

If anything, following recommended service intervals for your Mercedes – Lexus is more important in a higher mileage vehicle. Skipping oil changes or other services can lead to problems much more quickly than with a newer vehicle.

So, have your Placentia auto service advisor at Exclusive Motors help you with an assessment of your older car or truck. If you haven’t gotten around to a fuel system cleaning, or replacing power steering or brake fluid, a differential service or transmission service – it’s time to start taking care of those things. It’ll help keep you on the road for many more happy miles.

Fuel Saving Tip: Placentia Tune Up

Have you ever gone to Yorba Linda to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That’s why they tune up together.

Fuel Economy Now this is no surprise; I’m going to relate the orchestra to your car. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.

We call this, (ta-da) a tune-up. When an orchestra’s out of tune you get a bad concert. When your vehicle’s out of tune you get bad performance and bad fuel economy.

So check your owner’s manual for recommended tune-up intervals. Or ask your Placentia service advisor at Exclusive Motors what he thinks.

…Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Why is My Check Engine Light On?

The Check Engine Light strikes fear into the hearts of some Placentia car owners and is totally ignored by just as many. Just what it means is a mystery to most of us Placentia car owners.

Let’s get the urgency issues out of the way first. If your check engine light is flashing, that means that something is wrong that could cause vital engine damage. Naturally, you need to get that taken care of right away. If your check engine light is flashing, you shouldn’t drive at California expressway speeds, tow or haul heavy loads. Take it easy all the way to your Placentia service center.

Why is My Check Engine Light On?

If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn’t go off, schedule an appointment with your Friendly Exclusive Motors service specialist to get it checked out.

Some more Placentia information on how the Check Engine Light works may be informative for Placentia car owners. Most of your engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine condition and even the way you drive.

In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range the computer runs some tests and may turn on the Mercedes – Lexus’s Check Engine Light.

A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The computer doesn’t know if it’s a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine Light.

Now when you tighten up the gas cap the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since a bad reading didn’t come up again, it turns off the Check Engine Light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it’ll then turn off the Check Engine Light.

If the problem can’t be resolved then the light will remain on and you should get your Mercedes – Lexus looked at. Your Friendly Exclusive Motors service advisor will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give the technician a starting place as he diagnoses the cause of the problem.
