Swepco products

[911 tweaks]

I am interested in opinions on the Swepco products available these days. Please comment with specifics on their:
201 gear oil
105 hi impact grease
503 fuel improver
502 engine oil improver
any other items work great?

I am looking for info for: carbon deposit removal/mgt; fuel additive for improving engine longevity;... OR is all of this "additive" product a bunch of B.S.
Thanks to all!!

I replaced the tranny oil with swepco 201 and found that the shifting got easier and I was able to get into reverse faster. It seemed like it worked for me.

thanks jwmarc for your input. Anyone using the grease, fuel additive or engine oils?

Prior to putting in the 201 I would occasionally nick 1st and 2nd. I have been virtually nick free since then (1+ years) The only thing was it shifted a little stiffer.

I know, everyone says it shifts easier. But with me I noticed a little more resistance, but the synchros worked better. I have no idea what was in there from the PO, so it might have been a lighter weight gear oil, hence lighter forces, but less effective synchros.

I'll take the 201 any day vs. before, because the synchros work better (original 108K on tranny)

My $0.02

Out of curiosity, how much 201 is needed for the 915. Will one gallon be enough?
Thanks

[KNS]

One galllon will be enough with a little left over.

Thanks Kurt.

There are hundreds of posts on this if you use the search engine - pay particular attention to comments by Sherwood or Warren.

The more (direct) feedback I get about transmission oils, the more I learn which ones really stand out (both good & bad). While later model 911 transmissions ('87-on) with Borg Warner synchros do shift more smoothly with a high quality synthetic, there MAY be a penalty paid in terms of longevity of gear faces (R&P in particular), especially when racing is involved. The short of it: I hear both success stories and horror stories with synthetics, but I've never heard a horror story when a high quality dino oil (like Swepco) has been used.

the car in particular is an 82' SC. I am also trying to get feed back on the engine oil, #503 fuel trtmt and #105 grease offered by Swepco.

Specifically, is the swepco #503 fuel additive "better" than lubro molly "Jectron" or "Ventil Sauber" additives?

Are these quantifiable questions being asked or is there a LARGE AREA for interpertation as to how well these work??

I use the oil improver (502) and 201 for the tranny. I can't "prove" they help, but they make me feel better!

[911 tweaks]

thanks Art! Can you in any way quantify why you can conclude that they make you feel better? less noise...lower temp of something...easier shifting...burning less oil...better gas mileage...

Can you make any logical statement as to why you feel they are helping?
Anything... OR why not use nothing or something else?

911 Tweeks,

The Swepco 201 makes my tranny shift smoother and quieter and the oil improver quieted things a bit, too. No objective measurements, but it still makes me feel better. My mechanic said my tranny looks great and i have a "new" engine as my last one had 3 pulled head studs... I'll use the Swepco on my "new" engine" as soon as I get the car back on the road.

Pay particular attention to any post by 'Geary.' He knows more about this stuff than just about anyone.

Pay a lot less attention to me, but here's a thought: Swepco is not a company distinguished by its devotion to cutting edge lubricant development for Porsches or any other high-performance cars. Their 201 gear oil is basically a heavy equipment lube that happens to work well with the Porsche synchros in the 915 (up to 1986) transaxle. I wouldn't assume that any of its other products are ideal for 911's because of the fact that their 201 is such a good match. As I understand it, it's really just a fortunate coincidence.

Geary, Since you are spoken so highly of by Jack, do you have any comments on these other Swepco products? OR What are the best fluids to be using in an SC that will be driven hard on the street and see a few DE/Autocross events to begin with. The DE?Autocross use may or maynot expand after the experience has been tasted...

Please feel free to recommend(hopefully you use these products or did in a previous car) all fluids, additives, change intervals...to get the most enjoyment and longevity out of the car.

so what the best source ($$) for swepo 201 gear oil?

[Geary]

I haven't a clue about Swepco products other than their gear oil. I would imagine that it's all high quality.... and yes, I use Swepco 201 in my own car.

I appreciate Jack's kind words, but keep in mind that I'm merely digesting what I hear from a LOT of different sources, and relaying what the consensus is.

While Delvak 75/90 (synthetic) is what the ALMS guys all use, I've recently been getting some feedback from a couple guys using Swepco in identical sequential transmissions with excellent results (less wear on the gear faces).

host has it just under $50/gal

[sig_a]

Mobilube gearoil 75w90 (synthetic) is at least equal to Swepco 201. Ad claims Porsche uses it in all new 996's.

You do not want to use a synthetic in a 915.

From what Geary is saying, there may even be good reasons not to use synthetic in the G50.
