I've been told the magic elixir for the VR is 20w50 Amsoil Not sure I can verify that just yet but my VR is a bit quieter with it since I added it
Neogens are good tires for the money. Exceptionally quiet, sticky & easy to stretch. I had no problem with a 215 on a 9'" wheel.
I am also running castrol gtx 10w40 regular oil with the Lucas oil stabilizer on my vr. I had some light smoking issues before while running synthetic and switched over and it completely stopped.
I did notice lifter noise with the 5w-40 so decided to go with Castrol Syntec 10w-40 and it made quite a bit of difference in quieting down the lifters. I use a Mann filter. After i get the engine flushed on my VR swap using ****ty conventional oil, i'm going to run Castrol Syntec 10w-40 in it as well. Lots of people recommend 5w-40 or 0w-40 for the VR but i've found 10w-40 works well and my oil temps seldom exceed 208*.
On all these cars I have only used one method and found that the vr6 runs the best and smoothest on castrol gtx 10w40 regular oil with an addition of one litre of Lucas oil stabilizer lubricant every 2nd oil change. I absolutely love Lucas oil stabilizer treatment for my vr6s. It is such a thick lubricant that it comes out like honey and you have to squeeze it out. I swear I can tell a difference every time I use it. In any case, back to my personal theory, I have also had throughout the years experienced long time vw technicians tell me that the vr6 12 valve motor runs optimal on regular oil. They explained to me that the vr6 motor runs optimal when using thicker grades of regular oil compared to the less thicker blends of synthetic. I have even heard some people using diesel oil for their vr6. Apparently, the vr6 likes higher viscosity type oils because they don't breakdown as easily from the heat. The vr6 likes to run hot, more then most v6, and needs a thicker oil to lubricate against breakdowns. Synthetic oils can deal with heat breakdown well too, but I just think at the end of the day it does not compare. I don't know but I have noticed a difference. The current car I have now, mk2 gti golf vr6, was apparently running full synthetic before I swapped the motor in my car. So I did a engine flush and refilled it will my personal blend of castrol gtx 10w40 regular oil with the Lucas oil stabilizer and the car ran way better. Less engine noises, smoother idling, etc.
INSIST on a VW bumper...none of that "will fit" crap!
+1 Had these swapped onto the GTI from the GLI that I traded. On both, they were transformational. Exceptional dry grip, and almost as good in the rain. Amazingly low tire noise and pretty decent tread wear so far.
Just today I changed the rear brake pads and rotors on my 2004 Jetta GLI 1.8t. I got some new Zimmerman rotors and EBC Red Stuff pads on now, and obviously that fixed the grinding.
Love the car, but have just had the fuel pump replaced, driver-side window leak fixed, and a slight metallic rubbing sound related to the brakes(which the techs can't find yet.)
The NGK's listed have a colder heat range. Great in the summer, it will misfire like crazy in the winter
