Lately I have been wondering if I’m pushing my engine a bit too much on cold starts. In summer I start the car in the morning and wait about 1.5 min when the temp gauge moves up a notch. I then drive up a 30 foot ramp with a 40 degree incline (basement garage). Then about 100 yards later I’m on a freeway with an unposted speed limit. I get her up to 65mph keeping the RPM under 3.5 and cruise for about a min, by then the temp gauge is in the center. After that I let her rip (5 mins after engine start). Is this too hard too soon?

 

I would think you'd be fine..... the only thing that may suffer is the gas mileage.

 

At $0.72 / gallon of 95 Octane I couldn't care less about the mileage

 

Well that's just ....... not that I don't believe you, but still that's just.....



LOL! We need that kind of pricing here in the states lol.

 

You will be fine. As long as you give it until the temp gauge is up to normal, you are fine.

That being said....Just because the temp gauge shows normal, does not mean the oil temp is up to normal. It actually takes about 20 minutes or so of normal driving to get the oil temp. totally up. If you wanted MAXIMUM protection, you would not run it hard at all until after 20 minutes. How practical is that?? Not very. How many people do that? Not many. How many people have their engines last to 250K+ miles? A lot if they are maintained properly.

If the 4.6L Crown Vic's I drive at work can stand a 10F start and go screaming around town at WOT 20 seconds later...and last to 100K+ miles...you are fine.

 

Thanks Steve, now I don’t feel as bad for abusing my car, although I’ll never get to WOT 10 seconds after start.

Tom, I agree the price of gas is BS, however not here. Its complete BS in North America and even more absurd in Europe. The price of gas here is the actual cost, without any taxes or oil company profits. The price isn’t subsidized either, however the state owned oil company will not retain any earnings, it’s a strictly non-profit organization (just covers operating cost). How nice would that be back home?

 

Really nice Mike! Hey man take care and have fun with that car!

 

To be fair, most PDs are required to change to new CVPIs after 100k miles due to insurance reasons. Some of the auctioned off CVPIs with 100k miles have gone through at LEAST 1 automatic transmission, and the engine has shown signs of extreme wear/tear (excessive oil blowby, indicating worn rings). A typical auctioned CVPI w/ 100k miles will have had gone through 2 rebuilt 4R70Ws and has a very loose engine (burns through 1-2 qt every 1000 miles). The easiest way to tell if it has a rebuilt 4R7xx transmission is to see if there is an external in-line ATF filter on the left of the degas bottle. The SOP for installing a rebuilt transmission is to install an inline filter.

 

I didn't say the cars were like new at 100K miles, but I've never known any of our cars to have the amount of problems you've described.

I've never noticed any of our cars having much oil consumption issues, even the ones with 75K miles. And I don't remember in 2+ years of my service ever having to replace or even rebuild a tranny on any of our 10 Vic's in the fleet. They have all had fluid/filter changes at 30K miles, but nothing else.

Now our Animal Control truck, an 03 Chevy Silverado 2500...that thing is a piece! It has been in to the dealer 3 times for the tranny slipping, and had 2 fluid changes. It has 40K miles on it, and not very hard miles in comparison to the Vic's. Lots of city driving, but no WOT really. The A/C officer only goes WOT on foot if he is in hot pursuit of a stray Pit or cat.

 

How are your CVPIs driven? The NJSP cars that are generally used on the highway and go through transmissions pretty quickly. The first things to go are the OD bands or the mechanisms for going into 2nd or 3rd gear. Engine oil blowby is quite common as well.

 

wish I could get stationed in Kuwait now.

 

Ours are all in town cars. They have little or no highway miles. Most of them are stop sign to stop sign miles. We go through brakes every 9-10K miles. Conventional Valvoline oil changes every 3K, and probably the cheapest oil filters the local Valvoline Express Oil Change place can find. They are just plain white, not sure what brand or anything.

 

Would you please send me a couple hundred gallons??
Do you accept pay-pal??

 

I've seen dozens of P71's with 100K+ miles that run fine Quite a few with 200k. This one I had a week or two ago checked out pefectly fine in the shop

20 MINUTES TO LET IT WARM UP Come on, it takes me 9 minutes to get to work. That thing in the summer is up to temp in a minute or two.

 

Engine coolant temp only takes a few minutes. Oil temp, takes considerably longer. Full operating temp of the oil is around 210*F, + or- a few. If you datalog a little with the X-Cal, you will see what I am talking about.
