Best Practices - Engine Conditioner


1.      You can use the Diesel Engine Conditioner in a gas engine; you CANNOT use the Gas Engine Conditioner in a Diesel.

2.      Use one bottle in a 4cyl engine or 6cyl below 3 liter

3.      Use two bottles in 6cyl above a 3 liter and 8cyl small blocks (under 6 liters)

4.      3 bottles can be used in 5 liter 8cyl or larger especially for poorly maintained engines (still running)

5.      Before adding the Jilcat Proline Engine Conditioner do a regular oil/filter change

6.      When adding the motor oil leave 1 quart out to allow room for the Jilcat

7.      Allow the engine to run and warm to near operating temperature

8.      Once at temperature add the necessary amount of Jilcat into the oil

9.      Immediately drive the vehicle 30 to 50 miles, preferably on the freeway. Allow the product to circulate and bond with the heated metals.

10.  If the knocking, tapping or oil pressure issues have not been resolved make another drive of similar miles. This can be immediately or a following day.

11.  Allow regular use of the vehicle (if customer owned) and request they drive for approximately 2 weeks of their normal driving. Have them come back for another oil/filter change, if need be add one bottle of Jilcat Proline in with the oil.

12.  For Preventative Maintenance in inventory without a current issue, follow the above recommended amounts of Jilcat Proline based on engine size, drive 2 or 3 miles or allow an idle for about an hour and put your vehicle out for sale. Driving longer distances immediately after adding isn’t necessary, at least not the distance recommended for trouble engines.


Additional Information

  • There are multiple issues caused by sludge which do harm to the drivability of many vehicles.

  • Non leak Oil Loss, valve rattle or chatter, low end knocking, random loss of oil pressure, some timing issues and misfire codes all can be traced back to sludge, Jilcat has solved these issues.

  • Loss of power, fuel related codes, EGR issues, throttle body and fuel injector issues have been solved with Jilcat Fuel Conditioner (see below)

  •  Vibrations, hard shifting, slow engage, shudder and slipping have been stopped with Jilcat Proline Automatic Transmission Conditioners. There is a specific Transmission product for CVT Transmissions, Chrysler Plus 4, Multi Clutch and for more Traditional Automatics.

  • Differential issues from dragging, limited slip hangs, poor fuel economy from the excess friction can be solved using Jilcat Proline Transmission and Gear Oil Conditioner.

  • Use 1oz of the Transmission Conditioner for noisy or hard to operate power steering units


Products Available

There are products available for all vehicle components that are lubricated. Jilcat has a product for any type vehicle built. 2 cycle, 4 cycle, diesel, gas, natural gas engines. High performance, exotic, racing, synthetics included. There are products for cleaning fuel systems all the way to the convertors. We have products for weapons, farm equipment, large machinery, fabrication equipment and hydraulic systems. If it is metal and needs lubrication Jilcat Proline has the products. 

There are 4 non synthetic blends for transmissions: 

1.       Automatic Transmission – for the standard 4 or 5 speed auto transmission you find in most vehicles from the last 20 years.

2.       CVT – for all CVT transmissions on the market

3.       Chrysler +4 – Almost all Chrysler non CVT vehicles use a +4 auto transmission fluid, please verify what is called for by the manufacturer before adding any of the conditioner products

4.       Dual Clutch – many of the 6 to 8 speed transmissions and the multi shift (paddle shift) transmissions have a dual clutch setup that requires a different blend to function properly.

       All are available in synthetic and synthetic blends as well.

*Check the manufacturer specifications for fluid to be sure the correct conditioner is used.

Add one bottle of the correct Transmission Conditioner to the transmission fluid. DO NOT OVERFILL If you are draining the torque converter you can add a bottle to the convertor and a bottle to the transmission case as well.

If the transmission fluid is burned or dark, service the transmission and change the filter then replace the fluid using one bottle of Transmission Conditioner as part of the fluid quantity required on the fill. In my experience servicing a high mileage transmission usually causes more harm so we resist servicing if possible over 100K miles.

If the transmission is sealed you can remove a small amount of the fluid and pump in a bottle of the Transmission Conditioner. Most dealers service the sealed transmission and add the conditioner at that time.

In each situation the vehicle needs to be immediately driven 30 to 50 miles to allow the molecular process to take place and the “gunk” buildup to begin to dissolve.

We suggest GOOGLE the transmission for issues prior to any service. I have found many of todays transmissions have bulletins and may just require a computer update to correct a shift problem. The Acadia, Enclave, Terrain transmission has TSB’s involving the Wave Plate and if caught before 120,000 miles can be repaired by the dealership at little or no cost.

Fuel Conditioners

Pour 1 bottle into the fuel tank with 15 to 20 gallons of fuel. Best if the bottle is poured into the tank PRIOR to filling the tank to allow for blending before starting. Drive the vehicle as usual. If the vehicle has failed an emissions test, add the bottle to less fuel (10 to 12 gallons) and drive the vehicle 50 to 100 miles to allow the process to clean the system and effect the EGR and converters before returning for a retest.

The fuel product will lubricate the fuel pump and clean the buildup of gum, varnish or other gunk from the tank to the converters as the treated fuel is run through the system. The injectors or throttle body will be cleaned to bare metal and remain clean for several thousand miles.
