There was a time way back when automobile engines called for a straight 30w oil that the euphemism “Oil is Oil" had some validity. In those days engines were markedly simpler and internal tolerances were much greater than today's engines. Today's engines have very tight tolerances; the clearance between parts like bearing surfaces is less than half what it was 30 years ago. Most vehicles manufactured in the last ten years have variable valve timing. These engines have small passages in the engine block (that sludge easily) which supply oil pressure to the mechanism that uses oil pressure controlled by your car's computer to control valve timing. It's a great stride forward in making engines run well, more efficiently and with much more power. The downside to these improvements is they require engine oil to withstand higher temperatures and have much greater lubricity with a very thin film of oil.
What does this all mean? It means engine oil must perform better under much more extreme conditions! If it doesn't, engine wear increases and engine failures result. It means that with the proper engine oil and appropriate change intervals, your engine can easily last 200,000 – 300,000 miles, or you might have problems with sludging and failures at less than 100,000 miles with poor quality oil and over-due oil changes.
There is a lot to consider when choosing engine oil. We here at DAVCO Performance go to great lengths to choose the best oil for your car and carry it in stock. Not just for your engine either but for your transmission, differential and transfer case to name some others. I personally review the oils we stock, matching them to your vehicle manufacturer's recommendations along with the current API and ILSAC standards (American Petroleum institute and International Lubricant Standardization and Approval Committee.) The current API standards are SN, and ILSAC is GF5. You can find these designations on oil that meets their standards (usually on the back of the bottle). This is important to look for when shopping for oil; however, in truth most oils sold today meet those standards. SO WAIT! Is "Oil is Oil "not then still true? I mean there IS a standard that most oils meet???... Yes! But, not all!
AND THAT'S THE LOW END OF THE SCALE!
You see oil can just meet the standards or it can exceed the standards! This is very important to know particularly when choosing oil that will give your engine the most protection over its lifetime. Using an oil that exceeds the standards or has properties & additive package that's best tailored to your car is vitally important. Knowing how much sulfur, phosphorous and ash content that's in the oil helps balance the lubrication characteristics with how well that oil will treat costly components like your catalytic converter and O2 sensors. Catalytic converters are a costly item to replace if you don't change your oil frequently enough or your oil is high in things like sulfur and phosphorous that bind to the catalyst in your converter causing it to slowly degrade and eventually fail.

So your "Check Engine" or "Service Engine Soon" light is on? What to do?
I recently fielded a call from a car owner asking “how much was a smoke test?" Hmm, I thought “why?” So, I asked him why he felt he needed a "smoke test.” He responded explaining his check engine light was on, and he brought it to the parts store, they scanned it and told him that he needed a smoke test! Further, he would need either a charcoal canister or a vent valve.
Hmm, we hear this sort of thing a lot. ‘Diagnosis by trouble code,’ I call it. Great way to sell parts, but the wrong way to repair cars! Often I get these inquiries after the person has replaced the charcoal canister and vent valve and the light returned again after a few days.
So let's clear this up!
The check engine light illuminates when you have a problem that affects your vehicles emissions system. There are dozens of trouble codes that will cause the check engine light to come on! Many more will not. They will be stored in the computer memory of one or more of the modules that control your vehicle, yet some will not even turn the light on because they are unrelated to emissions.
Many ‘part store scan tools’ record only the most recent codes and, little if any other important information.
Simply a trouble code is not a diagnosis of a problem . Better, to think of it as a "road sign" pointing you in a direction toward your destination.
In this person's case, he had a code that indicated a problem with the evaporative emissions system. Which in some cases requires replacing a ‘charcoal canister or vent valve’ but, it could also be many other things as well.
A ‘smoke test’ is a quasi-technical term for testing the evaporative system for a leak (allowing fuel fumes to escape into the outside air.)
However, one doesn't jump into a ‘smoke test’ which takes time and can lead you down a "rabbit hole" without first performing some preliminary tests that rule out other causes that might initially seem to require a "’smoke test.’ Very often the problem is actually component related or a wiring problem.Often a ‘smoke test’ will reveal nothing when testing the charcoal canister because the smoke is absorbed by the charcoal giving a false negative result.
As I stated earlier, we see many people come to us after they have spent hundreds of dollars chasing a problem by installing parts that were in question because of a trouble code that led in that direction. Admittedly, some get lucky and land on the right part early on. Most spend money needlessly only to find out it was something much simpler than they thought, like a lose connection, cracked hose or other minor item needing replacement.
We would recommend leak testing the evap system based on some preliminary tests and evaluations that include scanning for codes but we also look at many other factors together, which help us evaluate and determine your problem quickly and accurately, usually in an hour or less.
Our equipment and knowledge is what makes the difference. Then if you need a ‘smoke test’ we move to that.
To sum it all up, we applaud those ‘do-it-yourselfers’ trying to save themselves some money. When it comes to a ‘check engine light’ you really are better off bringing it to the professionals.
We perform free scans and we are ASE certified technicians with many years of experience repairing just these sorts of problems.
Save your money have it professionally diagnosed and get the problem fixed right the first time every time, guaranteed!
We offer a FREE basic scan for trouble codes! So what do you have to lose , but a few minutes of your time to stop by and have it checked?
Give us a call or stop in! We are here to help!
Thanks again for listening!
We look forward to serving you in the future!

One of the biggest enemies of your car is the harsh Central New York winters. As long time Central New Yorkers ourselves, we know how to care for your car to protect it against CNY harsh elements. Going forward, I will present tips and advice on how to best care and prepare your car for each driving season.
We are now currently in the middle of winter and hopefully, despite how warm it has been lately, you have good snow or all-season tires already on your vehicle. If not, we can help. We offer new tires at very competitive pricing. We even store your off-season tires for free!
Cold weather is very hard on your car’s battery, causing extra draw and strain on a weak battery, which can result in your vehicle not starting when you need it most. We offer free battery tests to determine if your battery is up to the task, presented by Central New York winters. Come see us for your free battery check. Mention that you saw it on this blog, and we will test your charging system as well for free! During the months of January and February, if you purchase a new battery, you will get up to a $20 Visa Prepaid Card, which is good anywhere that takes Visa cards.
Look here in the future for other tips and recommendations on how best to glide through the rest of winter!
