Gas mileage after coolant flush


Emmanuel

Recommended Posts

1. Two days ago I flushed my Xterra radiator (refilled with Nissan OEM coolant)

2. I noticed this afternoon that my gas mileage DECREASED about 20%

So I was just asking myself : could 1 be the reason for 2 ?  Could it be related in a way or another ?

WOW, I also like to know if it's related but I highly doubt.

Btw, please share the coolant flush contact as I also need to flush my whole cooling system and refill.

Flushing coolant is an easy DIY job, why go to anyone. Thinking of my doing my ride over the weekend.

How to get rid of coolant inside the engine jacket?

Drain coolant from rad. Fill with water, drive around, flush, rinse and repeat for a few times until only water is coming out. Then refill with coolant. 

And you think if you go to "someone" they will flush it out? They will also just drain the rad and refill from top and be done with it

Since it’s a simple job I asked the small workshop in Al-Quoz where I go to wash my car Toolsa. Actually the Egyptian boss seems to be a good reliable mechanic. He usually works on classic cars.

I made a mistake in my first message, so edited right now : gas mileage decreased (not increased).

Even I am curious as to how this affected it... But if I were to guess maybe the Engine is running cooler with the new Coolant hence the ECU isn't having to compensate combustion cylinder cooling with the use of extra fuel (AKA running a bit leaner)? The only way I can relate the two.
