Frequently asked questions
My engine only holds 5 quarts of oil. Will 2 full bottles of Auto-Rx Plus overfill my oil?
Auto-Rx Plus is a metal cleaner and does not change your oil viscosity. Your Oil Reserve Is Much Larger Than 5 Quarts And Auto-Rx Plus Will Be Fine.
What is the shelf life of Auto-Rx Plus? Can I still use a bottle that has been sitting around awhile?
There is no known limit to shelf life for Auto-Rx® Plus.
What do I need to know about rotating seals?
Can Auto-Rx® Plus restore elasticity to seals and stop seals from leaking?
The answer to this question depends on the condition of the seals and the cause for the leak. Seals, especially those exposed to heat, stiffen over time. Seals that are torn, hardened with age, or simply beyond their service life need to be replaced. Seals may have a buildup of oxidized contaminant behind them that is in essence a false seal. After Auto-Rx® Plus has gently removed the contaminants fluids can then reach the seal. If there is life left in the seal Auto-Rx® Plus will restore its elasticity, allowing it to once again seal as intended. In the short term some leakage may occur.
Is Auto-Rx Plus compatible with my turbocharger?
Auto-Rx® Plus is compatible with the internal workings of turbochargers, their ball bearings, seals, etc. Turbochargers create a tremendous amount of heat. As a result turbochargers, and superchargers alike, can be quite taxing on motor oil and special lubricants. Life expectancy of a turbocharger is often linked to lubrication failure caused by heat. Auto-Rx® Plus safely removes oxidized contaminant allowing the turbocharger’s lubrication system to work as intended. As a result turbocharger life expectancy can be increased when Auto-Rx® Plus is used as directed.
What about the PCV valve? Do I need to replace it?
PCV stands for positive crankcase ventilation. The purpose of a PCV system is to re-direct blow-by gasses back into the combustion chamber, not allowing them to escape directly into the atmosphere. Some engine designs allow for a simple system, while others are quite complex containing many check valves and hoses. PCV systems should be serviced on a regular basis, especially on engines that are prone to experiencing sludge. A clogged or improperly working PCV system can lead to contamination of motor oil and eventually sludge build up. The makers of Auto-Rx® Plus suggest you always replace the PCV valve (if so equipped) from the original engine manufacturer. OEM PCV valves are engineered for proper flow characteristics; after-market valves may not meet the same specifications.
When is the Auto-Rx Plus treatment fully completed?
Is Auto-Rx the same as those solvent flushes found at the auto parts shop?
What is the Auto-Rx® Plus Maintenance Plan?
The maintenance plan is our Extended Performance Program. It is your assurance that the gains you received from your application will continue. Left unchecked, contaminants and sludge will return. For most engines a maintenance dose of 3 ounces with each oil change will maintain the benefits you received from your Auto-Rx® Plus application. For those engines that are prone to sludge, you should use 4 ounces as your maintenance dose. After a full cleaning has been completed, then you can maintain your engine on just the maintenance dose in the future.
How many times do I need to apply Auto-Rx® Plus?
We have seen customers get extraordinary results after only one application of Auto-Rx® Plus. One application is all that is needed. The exception is sludge-prone engines. Sludge prone engines have manufacturer design problems that leave them vulnerable. Using a maintenance does of Auto-Rx® Plus with each oil change will give you added security that a second cleaning will not be needed. If you’ve experienced sludge in the past, it is important to understand why it occurred and then take steps to prevent it in the future. Servicing the PCV system on a regular basis is one way to be proactive when it comes to sludge prevention.
