Speaking from experience as a Roush warranty repair provider, there were some very basic things that I was not happy with from them.
we have seen
oil consumption in the 1 per 250 range on more than a few units, it seemed to get better on the SRX motors , but we are now hearing they too are 1 per 450/500.
Spoken to several builders and shared what we have seen.
Bottom line, I wish Roush-Yates spent more time over at Roush-Roush.
