These are 235/85 rst16 Goodyear tariler tire...they have a 110 pound inflation recommendation.

I have a six horse gooseneck trailer wchich has Goodyear tires on it... they are about 4 years old and look fine, no appreciable wear and excellent sidewalls. I estaimate the mileage to be around 50,000 miles. Does anyone know how long i should run these? I have no problem repalcing them but...

Johnny, I have not seen much on the 25w50 Pennzoil...do you have any info??

A few of us racers are building Porsche 944 engines this winter and have had some minor machine work done to the crankshafts...The shop that did the work said that they do not want us to use synthetics because they foam and that the best oil is Pennzoil Racing 25w50. Now I have been using both...

Sounds like a scare tactic article. That author probably still uses candles and whale oil lanterns.

Porsche has indeed had a few engineering issues but many of these would only show up in cars that weren't maintained properly. Once you get behind on upkeep it can be problematic but in general the 911 engine is almost completely bulletproff. No other car maker has as many racing victories and...

Yessiree...sure is great to see the Porsche/Corvette duel continue to this day...I remember when the 1970's 911S had a 2.4 litre engine and the Vette had a 327 or a 454 CI. Guess which one won the drag race back then...Guess which one is still probably running on the original drivetrain! Sure...

I absolutely love my Audi A3 3.2 litre with DSG...single best car I've ever owned and one of the most fun and rewarding cars to drive as well. I have about 30,000 miles on it and need to get the tranny fluid changed soon.

Yup, that settles it...GM and Pontiac are certainly better than Porsche will ever be....

If you really examine the Corvettes that race in the American Lemans Series you will see that they are really not Corvettes at all...they are semi-tube framed purpose built cars manufactured by Pratt&Miller. Porsche runs a production based car with many of the same components that you'll see on...

The Chevy may perform well for a year or so...see what happens after it has a few miles on it...The Porsche will drive and feel tight as new even after 10 years. And there is much more to a cars overall performance capabilities than a Car and Driver test will ever show.

putting a new engine in the race car...any suggestions on what to use for the clutch spline? it will be a high temp environment.

This car is a DSG with Quattro. I am looking specifically for the rear diff fluid at this time. I hear the DSG trans is quite a pain to change the fluid in and actually requires a VAG COM to do it properly.

Wondering what is recommended for the rear diff on a 2007 Audi A3 Quattro. GL4 or GL5 or does it matter? The Audi part number makes no reference and it's $22/liter. I'd thought about using Redline 75w90 or Amsoil MTF.

Has anyone used the new Fleetguard diesel fuel additive? it is supposed to help protect diesel particulate filters and EGR systems on the newer light duty truck engines. Also, any idea where it can be purchased?

That does not seem to be the same as the specs that Valvoline qoutes on the oil...Interesting, i'd say that it looks pretty weak for a dedicated racing oil....

I had some Mobil 1 synthetic grease in a dispenser and may have mixed it with Amsoil 2000 racing grease...is this likely to cause a problem and should i clean and repack?

My 62 Austin Healey likes Castrol High Mileage 20w50

talk to Doug! he is a wealth of knowledge and knows Porsches as well.

Why mess around? Run the M1 ow40.
