Where is the best place to buy Archoil?
:hahaHarry gets my vote. Need to order a gallon myself. I also use both the oil and fuel treatment. Butter is a good analogy. Mine must run like melted butter then, just a little warmer than Weld's.
If you block off the EGR cooler you will get a CEL (check engine light) and the engine will de-tune itself. Whenever a delete is done the cost of a SCT and tunes need to be added in. Truck will run just not as well.:usflag Thanks harry6.0 that will be done at same time as I already have the coolant zerex ZRXED-1. I am leaving the EGR just removing the Cooler and blocking the Exhust. This is on hold for a while as just had a Knee replacement.
