I haven't had a chance to do anything since the weather has been pretty terrible lately, with snow and rain every weekend. I'll probably get to it within the next 1-2 weeks but for now, I can say that my fuel economy has been dipping to 19.7 MPG with the Ruthenium's.Update?
Update?
Name | Resistance (kOhms/kΩ) |
Bank 1 | 4.24 - 4.27 |
Bank 2 | 4.31 - 4.32 |
Bank 3 | 4.08 - 4.09 |
Bank 4 | 4.72 - 4.73 |
Yes, I haven't had a chance to do a full fill up yet so no comment on the gas MPG but in terms of going back from the different types of plugs, it seems like the Iridium's are more smooth/refined when accelerating. The difference isn't massive but it's subtle enough to notice the change.Did you drive the car over the weekend/Monday?
I relaize you probably haven't gotten through a tank to comment fully on MPG, but any other drivability opinions since you've driven it a bit more (we assume)?The difference isn't massive but it's subtle enough to notice the change.
I honestly think there's not much of a difference in terms of driving dynamics. It's probably not really worth testing out unless you have a turbo but for the CX-5 2.5L, no real discernable difference.I relaize you probably haven't gotten through a tank to comment fully on MPG, but any other drivability opinions since you've driven it a bit more (we assume)?
Hey AzianAssassi, yes my MPG returned to normal after swapping back to the original plugs that were meant for the car. I didn't record much data as I went strictly off my odometer MPG after each fill up and it seemed less than usual after installing the Ruthenium plugs.I think I'm going to try out these myself. Give us some more data. Did your MPGs get back to norm OP?
Oh sorry, I meant I wanted to add to the data available.Hey AzianAssassi, yes my MPG returned to normal after swapping back to the original plugs that were meant for the car.

Any particular reason you wanted to try out the Ruthenium plugs?
Ruthenium HX™ brings the most advanced spark plug technology to the automotive aftermarket, delivering better efficiency and power for today’s engines.
NGK’s patented ruthenium technology stands up better to wear to bring maximum durability and performance to your engine.
Ruthenium HX is available in two designs to best maximize the performance of your engine.
DFE (double fine electrode) maximizes ignitability, while reducing emissions for low-heat engines. This NGK-patented design is recommended for non-turbo applications.
PSPE® (projected square platinum electrode) provides the best ignitability and service life for high-heat engines. This NGK-patented design is recommended for turbo and supercharged engines.
Can you let us know if you also experience the carbon buildup around the pistons/cylinders ?Also I would be remiss to not mention, NGK Rutheniums come in two flavors:
Unfortunately I don't have a snake camera yet. I should've looked during Cyber Monday but I will try to remember to do a 5k miles check up of the plugs for comparison. I expect to see what Dig experienced.Can you let us know if you also experience the carbon buildup around the pistons/cylinders ?
If possible, maybe some before/after photos to compare?
Also, because it's a skyactiv high compression engine, would the PSPE be the choice regardless of whether it's turbo or non-turbo?
