Thanks folks...... I'll try the Auto-Rx.

I'm a total detailing novice but here's my 2c. I just waxed my black Porsche with Girots liquid wax applied with a Girots wax pad on his orbital machine. Followed his insane method to apply three coats three hours apart without buffing between coats. Apply the last coat and let dry for 12 hours...

This may be kind of a crazy question but: I have a 1998 Vovlo V70 with 285k miles on it. The steering rack is basically shot and it leaks AFT to the tune of about 12 oz./ week. I've got a couple of containers of stuff I'd like to get rid of one being Slick 50 the other 80-90wt gear oil. Can I...

I currently have one of the 911's on Mobile 1 0W-40 - it took a long time for me to come to terms with both a sythetic (leak worries) and lower weight oil. Now quite a bit has come out about Mobile reformulating all their synthetics with lower ZDDP to aid in the new cat converter. Problem is...

Sorry should have included more info in the original post. The 1985 911's are air cooled.

Thanks. I should have also mentioned these are normally aspirated cars for pleasure use only - they don't see track time. I don't mind changing the oil frequently since it's pretty easy and I like the added advantage of changing the filter. I know the Brad Penn has high shear properties so if...

I've chosen two oils for use in our two 1985 Porsche 911's. One is Brad Penn Grade 1 20W-50 racing oil and the other is Amsoil Synthetic 20W-50. Both have suitable levels of ZDDP for adequate tappet protection. My question is - I plan on changing the dino at 3-3,500 mile internals. Is the only...

As always......Thank You all for providing valuable information and an overall education into properties imparted by various lubricant additives. I've decided on two oils: dino - Brad Penn Racing 20w-50 synthetic - Amsoil ARO 20W-50 both come higly recommended by those with a greater knowledge...

Hoping you oil folks can help. My 1985 911 3.2 litre originally used dino 20W-50 oil. Porsche has approved Mobil 0W-40 for all cars back to late 70's. Now I'm hearing Mobil 1 15w-50 might be the better choice. Also hearing Mobil may not have enough zinc and phosphorous for proper lubrication in...

moribundman - just wanted to answer your question about operating temp. When the engine is fully warmed up it should run somewhere between 180 and 210F. Thanks for your advise.......

Moribundman, Thank you for your input. My 1985 Porsche has 50k original miles - would that alleviate your concerns about the 0W-40. If not, please elaborate the basis of your concerns. I was thinking of using the 0W-40 for cold weather months. I've also had recommendations from some independant...

Thanks again .........

Just wanted to thank everyone for the valuable advise that was provided. Based on recommendations here and on the Porsche Club of America site I've decided to abandom my previous 'leaking' fears and make the conversion to Mobil 1 0W-40. I went to a local store last night to price the stuff and...

Hi folks, Just joined today and I already have a question for those more knowledgable than I. I recently purchased a 1985 Porsche 911 Carerra for my wifes 50th birthday. The manual lists SAE 20W-50 as the oil of choice for my geographical location which is Connecticut. This is an air cooled...
