Can I get a PM with that 'big discount' code? I need to restock up on the HSS goods. Been running the Everyday treatment and every 5-8 tanks I run the extreme through it...I run the Hot Shot See (HSS) products on both my diesel.
HSS EDT - every tank fill-up, mostly to increase lubricity for the fuel system. That's my single greatest concern. I only gas up at Shell and Exxon.
HSS Diesel Extreme - once or twice a year just to keep everything clean.
HSS FR3 or Liquimoly Ceratec - oil additive package with each wheel change.
Is it worth it? first of all I buy the hot shot secret products at a big discount. Did you some really good deals on supplying additional free product and free shipping when you buy. So I don't find the cost to be that much. FR3 is really impressive. I can barely hear the engine run when I have that in the oil.
On the rest we don't know. Cheap insurance hopefully.
