Hey everyone, a lil question here

I travel a lot between cities, almost every other weekend i go to riyadh( around 450 Kms ) and come back ......
so a question, cuz i usually drive my '10 SRT8 on 140 -160 kmph.......
but on the way for aroun 200 km or more, I take it too 180-220 kmph...

is it bad? like if i drive at this speed for longer period of 200kms? or is it okay? the JEEP made it for this reason ? :D

and ya one more thing.........

When i floor it from a dig, after lik a couple of minutes, there is this strange smell of the engine, like petrolish or something, is this normal? it goes away on it own, in a minute too!......

It's worse than a slower speed, but higher speed will always be worse. 220 is not that high even for an extended period of time, and should not add any stress above what can be handled. You should be just fine, just make sure to check your oil frequently.

I also get that smell on my 2010 after WOT runs *shrugs*
