OK asked macanic today about bringing my VQ up in the revs like 5-6 maybe 4 i didnt say 6 cause i didnt want him to flip on me well he said he would stay away from 5 cause it puts extra strain on the engine that is not worth it well i love doin it and i just changed to synthetic oil today and even love reving more after today give me some tips please...

bad or good ? borderline ??

 

Sure reving the engine up high puts more "strain" than leaving it at idle, but if reving the engine to 5-6k was that bad, than the redline should be before 5k............notice any difference after adding the synthetic?

 

High engine speeds put high stress on engine bearings, connecting rods, piston rings, and the valve train. It accelerates wear on moving parts and shortens the life of the engine. If you love driving at high revs, go right ahead, but don't kid yourself about the consequences.

 

Maybe you don't understand the meaning of the tachometer red line.

Running the engine at speeds approaching the red line incurs the cost of accelerated engine wear. That means your engine will die sooner than it would if driven moderately.

Running the engine at speeds in excess of the red line incurs the risk of immediate catastrophic damage. That means something is likely to break right now.

 

And not to mention, terrible fuel economy.

Matty, you may like the way it sounds but if you love your car that much, take good care of it. High revving is unnecessary especailly when your usable torque to get the car going is under 3000 RPM.

 

I redline my car several times on each trip across town. In other words, I drive the pi$$ out of it. I havent heard a peep out of the engine at all in 123000 miles. It runs just as smoothly, and gets better fual economy than it did new.

I am talking about fuel economy while doing the high revving.

 

I am talking about overall fuel economy.

 

Well, we are making points on 2 different subjects. Overall, yes, when the engine is broken in, it is more efficient. When your revving all over the place it's not efficient and still causes more wear and stress like Daniel specified.

 

Im scared now I dont feel any difference with the synthetic but im only trying it out ill probably go back after 6 K miles...

 

Well, to be safe, I'll try to keep my rpms as low as possible at all times. Forget 3000 rpms, I can do it in 2000 rpms! Just don't honk at me dammitt!!!!! LOL
