“We use Conklin’s vehicle products, and yes, you can get better mileage with them—and sometimes  it’s big numbers.
But the real value is how long we run these trucks without having to do major repairs.
Between our work trucks and our personal vehicles, nothing has an easy life, and we go years without having to touch anything.”
-Ben Welsh
“The secret to this vehicle’s long life is using the Conklin lubes and conditioners; a person  can keep the complete system extremely clean and well-lubricated.”
With the most current mileage at 910,000, Ben is still as happy with his Suburban’s performance  as the day he purchased it.
He says it still runs incredibly smooth and has next to no oil consumption. PLEASE NOTE: Conklin recommends using in switching to using Convoy oil. How to Convert to Convoy® Motor Oil: When converting an engine from conventional motor oil to Convoy,it is important to first clean any sludge and deposits from the crankcase with . 1. For new vehicles with less than 20,000 miles you can use Convoy at the next oil and filter change interval. 2. If your vehicle has 20,000-100,000 miles, run and conventional motor oil for 3,000 miles before switching to Convoy. 3. For engines over 100,000 miles, it may be necessary to run more than the one oil change interval. Keep in mind you can’t run too many times. When first running , you may notice a slight increase in oil consumption. This is normal. The increased oil consumption is a result of the sludge and deposits burning off. Once you have converted to Convoy, you will no longer need to run . Always change oil filter when changing oil. Please see our other listings to purchase
