Buy them in bulk from RockAuto. Do NOT buy them from Amazon. I've been using Wix for a long time and recently switched to the Wix XP because it's only a few extra bucks.
The whole reason they charge the battery less is to work the alternator less and save gas. I wonder if this was worth the micro change in MPG numbers. Doubt it.
I'm sorry to hear this happened to you. I'm glad it happened within your warranty period though.
I'm still guessing they screwed up your initial service you had. It sounds like you said things started acting up after the service? That indicates improper maintenance to me. Unfortunately it's...
Are you sure it was the PTU you had them service and not the Transmission?
Can you post the Work order from that service?
Welp, its really sounding like the Dealership screwed up your initial service you had them do. Im guessing they drained either the PTU or Transmission and didnt fill it...
I changed mine at 10k and visually looking at the fluid, you could clearly see break in metals dispersed in the fluid.
I'll send in a sample to Blackstone when I change it again at 30k. It will be an interesting contrast to this sample.
Can people please state what altitude they live/or mostly driving at?
Altitude has a huge effect on this. And these "expirements" mean mostly nothing without this factor included.
I live at 6000 feet and 87 octane is more than adequate for the ecoboost at this elevation.
