If you are using a top quality full synthetic oil of an appropriate viscosity, aftermarket additives’ are a total waste of money. Most are short term “band-aid” products that do little if anything good. Some can actually have a negative effect on the oil itself.

i agree to a point i ran a largish repair shop for 20 odd yrs so have a bit of an idea. as i pointed out im not talking about the products that are pretty much oil thickners and band-aids as you rightly say.but there r some very good mostly teflon based products out there. some are used by large manufacturers to coat turbo bearings etc on new cars and trucks to protect on start up and i see from the many posts on here re start up noise [from top end ]maybe a little help might be a good preventative tactic. thay work on a molecular level and in simple terms stick to the surface of the metal rather than draining down when engine is standing thus protecting it for the second or so the until the oil is upto pressure and circulating to all parts of the engine as on more conventional type engines the 1st place the oil is fed to is the mains and end shells and was wondering if this was allso the case with a boxer type set up cheers dave

I remember contemplating using this stuff, and have kept this thread around as a reminder why not to try it:

My personal favorite:

Shell bought the SL50 brand name and pawned it off on Quaker State, who thankfully doesn't put PTFE resin in their formula. It's likely a harmless additive booster at best....maybe some seal conditioner.

Definitely falls into the "feel good" category.

Folks, there simply isn't an additive that lube engineers ~forgot~ or were too cheap to include. The add pack is a system, where all the constituents need to be in balanced proportions, don't think you can "improve it".

Check out the additive supplier's sites, like Lubrizol...

Best to just use a HiMiles oil, 10w-40 unless you see below zero F or do mostly short trip driving.

If you want something modern and high tech, try the Conoco oils with Titanium, like Kendall. The Ti gets worked into the engine metal parts, it's no joke.

      I'm new to the Porsche family.... Just over a month and the proud owner of a 1999 Boxster.  It's a project car but still on the road and my point to point ride.  Must say, LOVE to drive this car....This one has  been lowered some, well alot... and does it hug the road..... Just doesn't miss much being that low....  My question is, I am having an issue with the rear lights on this car...  I know I had a problem with the left rear brake light.  I tried tracing back the wire but found no problem... I then switched the lamp holder from the right side to the left and all the lights worked... So I thought I had an equipment issue.  I bought a (Porsche) replacement bulb holder.  Came in last night.  Changed out today...Guess what????  Turn indicators work, Backup lights work,  Brake light works on the Right Side ONLY, (still) Now no rear tail lights what so ever......I have checked ALL the fuses, only had to replace one and it had nothing to do with the lights.  NOTHING has changed....Where did my tail lights go??????  Can't figure this out.......Please help.......Just FYI,  ALL the LIGHTS were working as of last Wed. when I did the bulb holder swap and checking the lights.  Power is to both wire harnesses.   Everything else works except the left brake light and the drive lights.  Go figure.......

      Hello-
       
      I'm new to this website. Here is a  question:
       
      I have a 1998 Boxster 2.5 Tiptronic. I just had a new key programmed at dealership ( the old key fob newer worked). With new key fob, all doors  (including gas) lock and unlock appropriately. However, when pressing the button to open the rear trunk lid, the lid doesn't move and the rear lock actuator/solenoid is silent.   I disconnected the actuator from the car (separating the plastic connector) and using a 9v battery, made the actuator ( and lock) open and close. So I believe the problem is not the actuator. I also connected a volt meter to the two wires that connect from the car to the actuator,  then pressed the fob button, and no voltage was recorded. However, the red light on the fob and the red light on the dash near the windshield did light up 
       
      So i believe the problem lies in the electrical system somewhere between the actuator and the fob. Any ideas on how to test the wiring running from the trunk lock actuator to the CLU? immobilizer? or wherever it goes?   Or should I be spending my time evaluating the CLU? immobilizer? ??
       
      Thanks for any advise!

      I am missing the shift knob insert to my Boxster S 6 speed and cannot find a replacement anywhere without having to buy a whole new shifter... Does anyone
      have one they would like to donate or sale? Or does anyone have any ideas on how to get one. Its just the insert that fits on top of the shifter Reverse through 6th...
      Or does anyone have any ideas on how to make one? I am at a loss and it looks raty without the insert..... 
       
      Thanks in Advance!

      Boxster 2003 window on passenger side will not drop to open the door with either inside or outside handle.  I replaced the micro switch from the outside handle to no effect.  Windows drop with unlocking top.  Driver door works normally.  Inside window switch works with no noises from regulator.

      Hi all,I know that there has been a lot of talk regarding fitting rear speakers to a 981 Boxster . I have a 2014 GTS with sound system plus and I am very keen to add speakers behind the seats to fill in the sound. Is there a way of either enabling the fader on the PCM and then wiring the rear speakers to the amplifier under the seat ? Alternatively,connecting the rear speakers with a resistor of 16 ohms in parallel with the front speakers?
