driving below 2800 RPM = trouble?

What does "lug the engine" mean?

I've heard of this lower RPM's = IMS failure as well.

Thankfully I’m always driving between 4-7K RPM..I like using lower gears while cruising...3rd usually up to 65-75 MPH.

how much of this applies to Tiptronic transmission boxsters? (probably a dumb question)

also on my Tip, how long is it "safe" to stay in first when first starting the car?

i'm always in a rush to get it to 2nd (as it stays above first until you turn the car off)

I would also like to hear something on this as I have a tip. I thought I read somewhere that tips are not as prone to IMS failures as manuals are, but is that because there are more manual cars out there? I try to wind mine up as much as possible once she's warm, but I am in a lot of stop and go traffic.

That's like when you slow down to pay a highway toll and then you try to take off with the car still in 5 or 6th gear because you're too lazy to downshift.


My lazy move is skipping 5th gear. I go from 4th to 6th. So I think that's kinda like lugging..

p.s.
There's a case of RP 5W40 sitting at a local NAPA dealer. They're wanting like $12 a quart. I don't mind the price but Castrol Syntec is like half the price. Is it really twice as good? I've seen the load machine tests but I'm not sure how real world they are. And of the dozens of oils that Porsche has tested and recommeded why isn't RP in there? Is it purely business?

The Tiptronic cars are less prone to RMS failure... NOT IMS failure.

This is most likely because there is no direct mechanical link to the crankshaft. With a torque convertor, the link is fluid, with a clutch, it's mechanical.

Ahhh, thanks for the clarification. Wishful thinking on my part But, I guess if you are running a tip car in the Drive mode the transmission will keep the engine from "lugging" with the downshifts. Which from the sound of it is a good thing.

Good point. In fact, I'm in Drive about 99% of the time unless I get in slow traffic, or on a 25MPH Pkwy. Then I go manual and usually stay a gear below what the dme would otherwise do in order to keep the revs up.

Don't forget, both your oil pump and your waterpump are rpm dependent!

Here I am checking the forum on Saturday morning at 5:45 am waiting for the wife to order me around to set up tables for her garage sale and I read this thread.

It warms my heart to no end that my gut feeling is right when I'm behind the wheel of my Boxster:

DRIVE IT LIKE YOU STOLE IT ... it's good for the motor.

I'd rather wear out the motor from increased friction than have an IMS failure because I babied the thing. When my motor blows, it had better be due to being thrashed for many many miles, not babied too much.

Now I must go out and set up tables in the dark and take orders from "the Boss."

How much for this coffee pot? And for these garden tools? And what about the plastic pig holding flowers? I don't see a price on the Boxster?
