Egr cleaner spray , worthwhile or not?

  1. My model of MX-5 is: __
  2. I’m based near: __
  3. I’m looking for technical help or recommendations on: __

Having read forum posts regarding the difficulty in gaining access to egr on the NC just wondering if any owners have tried this or similar products.

If so what’s your opinions ?

Thanks in advance.

Hmm, it may well clean the inlet tract of breather oil and possible EGR deposits, same as most carb-cleaners; but the bit that fails in the EGR loop, the valve, is full of exhaust gases only, and their carbon/sulphur deposits (if any) are the eventual problem. This can will not touch that in a simple squirt.

However, running the correct lean-burn mixture (no hint of black or sooty exhaust) and a good “cleaning” petrol (eg V-Power) will keep the EGR loop in much better shape. This also makes economic sense.
