Give it several 1-hour+ blasts on back roads with plenty of Techron gas fill-up treatments.

I might just be old-fashioned, but have 87K+ miles on my '95 and engine is dry as a bone and I get 3Kmiles/qt of oil. No problems passing PA emission checks.

There's nothing wrong with 2 heat/cool cycles daily. Why does it matter how many heat/cool cycles happen in a day? I drive mine 4 or more days a week and that means 2 cycles at least each day. I feel it's important to take it to redline a couple times every time it's warmed up to blow it out a bit. Use the damn car and drive it hard. Use from frickin' techron and ENJOY IT! ........i never understood the philosophy of owning something so fun to drive and only driving it once a week. Wht buy the damn thing in the first place. Go get a fine peice of art and hang it on your wall instead if that's your philosophy.

Arrwin,
Good point. But a little stop and go isn't going to kill the car. Fortunately my commute is on the freeway typically with some room to run a little. Unfortunately I get caught in it from time to time. That doesn't mean I'm going to stop driving it.

Good luck.

There is a very good DIY article on this I believe on Robin's site. I can understand not wanting to deal with this as soon as you get the car, but it's becoming less of a big deal, if SAI ports are the only cause of the CEL. I live in a horrible traffic area and had to take the 993 to work yesterday to drop it off at a shop for the clear-bra install. I still managed to redline it every chance I got. I don't care about gas mileage. I care about smiles per miles and beating the hell out of my car. I have found on all three of my 911's that the harder I drove them, the better they got.

If they are gonna pay to do top-end work, make sure you find out which machine shop they are gonna use to redo the valve guides and find out from that machine shop what type of guide materials they are gonna use. OEM material is unacceptable as a replacement. Check some of Adrienne's threads as she recently got top-end work done or search through some of Steve Weiner's threads as he is the guru. FWIW, I believe Truspeed paid for top-end work for Agro.

I have not experience CEL - well at least yet. I use Techron every 2K miles. I normally drive my car at least 30 minutes for any trip, and oil thermo is open. I plan switch off to BG as this chemicals may provide bit different cleaning action.

More threads in the archives on this subject than you can shake a stick at.

I know the temp is a factor as well...how hot does it get there (extremes)? What weight oil do you use?

Is it beneficial to use Techron more often, rather than just before oil changes or will is there no benefits since the contaminants are still floating around in the system?
