Frequently asked questions.

WHY SHOULD I BUY YOUR PRODUCT?

ENTEK Smokeless Motor Oil is the number one selling product in the world that guarantees to STOP oil smoke tailpipe emissions in all internal combustion engines regardless of engine brand, the age of the engine, or the reason for the oil smoke emissions. There are no exceptions!

HOW DOES YOUR PRODUCT WORK?

Quite simply, ENTEK Smokeless Motor Oil will STOP, not cut down or greatly reduce, but ABSOLUTELY STOP all traces of engine oil smoke emissions at the tail pipe with a simple oil and filter change. Additionally, ENTEK Smokeless Motor Oil has special properties that aid in the prevention of oil leaks and assist in retarding burn-off.

DO YOU JUST ADD THE PRODUCT TO YOUR OIL?

No, you don’t; ENTEK Smokeless Motor Oil is not an additive, and its use with any additive will void the unconditional three-way money-back guarantee. ENTEK Smokeless Motor Oil is a completely synthetic lubricant and is to be used just as you would any petroleum-based motor oil, in that you simply change your oil, installing a new oil filter, and that’s it! You are ready to proudly drive your previous, embarrassing, oil-smoke-emitting vehicle anywhere, knowing that you will be able to pass even the most rigid emission control tests in the world!

DOES THIS MEAN THAT MY VEHICLE WILL PASS EMISSION TESTS THAT IT PREVIOUSLY FAILED?

In a word, ABSOLUTELY! It’s guaranteed under our exclusive three-way money-back guarantee.

WHY DO I NEED SMOKELESS OIL?

You only ‘need’ ENTEK Smokeless Motor Oil if you have an otherwise serviceable automobile that emits a haze of blue oil smoke; however, many consumers comment on the fact that they experience a noticeable improvement in gas mileage with the use of ENTEK Smokeless Motor Oil.


WHAT IS THE DIFFERENCE BETWEEN SMOKELESS OIL AND REGULAR OIL?

There are several differences, but the most obvious is the fact that ‘regular’ oils are petroleum-based, while ENTEK Smokeless Motor Oil is a man-made synthetic lubricant.


IF THE PRODUCT DOESN’T WORK, CAN I RETURN IT?

Yes. We offer ENTEK Three-Way Money-Back Guarantee.

HOW OFTEN DO YOU HAVE ENTEK SMOKELESS MOTOR RETURNED BECAUSE IT DIDN’T WORK?


Our return rate is .00167 percent or less than two cases per thousand; however, that is not because it did not work as we claim that it does, but it is because there was not a proper diagnosis made of the emission that was occurring. This is the primary reason that we do not actively seek sales from non-automotive professionals. The non-professional will immediately conclude that any tailpipe emission is oil smoke, and they are frequently mistaken as to the source of the particular emission. The emission is frequently the result of a blown head gasket, a cracked cylinder head, or even a broken engine block, so in these cases, ENTEK Smokeless Motor Oil will not help resolve the issue.


WHEN I CHANGE THE OIL THE NEXT TIME, WILL IT STILL NOT SMOKE?

Your vehicle will not smoke as long as you continue to use ENTEK Smokeless Motor Oil; however, if you discontinue its use, use any additive or top off your oil level with any oil other than ENTEK Smokeless Motor Oil, you can expect your vehicle to start smoking once again.


HOW OFTEN SHOULD I CHANGE MY OIL?

We have several inner city groups of users that change their oil every 2,500 to 3,000 miles, while some of our users who drive almost exclusively on the open highways regularly drive 8,000 to 10,000 miles between changes. Just as with any high-quality lubricant, good judgment in relation to the severity of the task should always prevail.


IS THIS WEBSITE THE ONLY PLACE YOU SELL YOUR PRODUCT?

ENTEK Smokeless Motor Oil and Mr. BLOCKHEAD can be purchased on this site www.SmokelessOil.com, on Amazon.com, or through our live call center at 888-670-4300.


WHAT DOES MR. BLOCKHEAD DO?

Three-Way Money-Back Guarantee

GUARANTEED TO PROFESSIONALLY LICENSED USERS*

ENTEK Corporation products carry our exclusive Three-Way Money-Back Guarantee.  If they fail to perform exactly as we claim that they will, you will be entitled to:

1) A full refund of your purchase price.
2) A full refund of your shipping charges.
3) We will issue a pickup order, and we will pay for the return of the unused portion of your order to our warehouse.  You have nothing to lose.

*It is necessary for us to limit our Three-Way Money-Back Guarantee to licensed automotive professional users only. The reason for this is that non-professionals frequently assume that any emission is oil smoke. Although this is usually the case, emissions can occasionally result from an improper fuel-to-air ratio, a blown head gasket, a cracked head, or a break in the engine block.  We cannot accept responsibility for misdiagnosing an emission issue.  The cost of a return for misdiagnosis is overwhelmingly expensive for ENTEK Corporation. 

If you have questions or concerns that are not addressed on the FAQs portion of the ENTEK Corporation website, please feel free to call our Field Office Service number, and we will be happy to answer any additional questions that you might have. Our primary goal is for ENTEK Corporation customers to receive the very best in customer service as well as the very best in our consumer products.  If we ever fall short in meeting these goals, we want you to contact us immediately with any complaint or any suggestion that may help us improve our service or products.
