I was driving the interstate yesterday ohh at about 50-60mph and decided to gun it, I watched the tach while the truck gained speed, 62000 rpms ... I haven't done a dead stop run yet, what does yalls tach read?

I am trying my best to keep the engine at low rpms, until I reach 3000 miles. I plan on doing its first oil change at 1500, 3000, & 6000.
I dont see what harm it can do, plus the 1st 2 oil changes are free, if the dealership will allow this.
I've installed many engines, and I am a firm believer on doing the 1st 3 oil changes at those mileages. .
Anyone else out there doing this?

 

I think you misread the tach.

Break in oil changes are no longer necessary in modern cars. Will it hurt, not in the least. Will the dealership give it to you as your free changes. That's up to them.

 

LMAO 62000 is a bit much huh DOH!!!
dang ol coffee jitters

 

Drive it like you stole it and it will run great for years!!!!!!

 

although i drive it like i rented it!

 

While accelarating to get on the interstate, mine often goes past 5,000 rpms. I was kind of shocked at that except it normally runs at almost 3,000 rpms at 75 mph. My other car ran at 2,200 at that speed.

Am I correct that the oil needs to be changed more often when the rpms are higher?

 

Use a quality oil and you`ll be fine. 3k for regular 5k for synthetic.

 

got back from a midnight run to Wallyworld, set the cruise on at 65mph, tach read at 2500rpms, 18-21 mpg, on the way home I drove 70mph with the cruise about the same rpms maybe 2600, 24-26mpg, got worse gas mileage going downhill than uphill, and terrible mileage rolling behind a semi about 6 cars back.
I have gotten 31mpg flat road with the cruise set to 65mph.
