just changed oil tonight... Mobil 1 0W-40 (VW 502.00 approved) along with a Mobil 1 M1-205 filter... It's my second one, no issues with the first one...
Hawk HPS with the rear pads almost worn & the front pads were about 70% worn---new rotors all around. Just for kicks, I decided to get ATE Slotted rotors, tyrol caliper bushings & a fresh fluid flush....
i have been told at the dealer that new thickness is approx 25 mm, and replacement size is 23 mm... VW recommends they be done together, but backyard experts & penny pinchers feel that it isn't necessary...... I would never take a chance for the $200 or so that rotors cost it just isn't worth it. if you can't afford $200 for the most critical safety system on your car, perhaps you should take the bus until you can... Very small diameter diferences cause degradation of brake performance, witness when the pads are half worn how low the fluid goes down....that is compensating for the pad wear and ROTOR wear as well......tires & brakes are all that saves your butt in the day-to-day world of insanity out there, don't be foolish.
Contrary to what some people think, the rotors are designed to be replaced when the pads have fully worn down. The tolerance for allowable thickness on our rotors is very small. I don't know the exact number off the top of my head, but IIRC the front rotors on your Jetta are 25mm thick when brand new and the minimum thickness is 23mm. That's not a lot of wiggle room. When the pads are fully gone the rotors will be very close to minimum thickness. You can mic the rotors to test the thickness, but made sure you get past the \"lip\" on the very edge of the rotor or you will get a false reading. Personally, I say don't mess around with brakes. If you only have a few thousand miles on the rotor, than fine - keep it. But if the pads are gone, the rotors are gone too. On a somewhat related note, I just did the brakes on a 2006 Mini for a friend of mine. The tolerance between min and max thickness was only 1.6mm on the front rotors! That's tight.
So, I went ahead with the Autolite XP iridium plugs. Right now, I cannot complain. Everything is running pretty good. I put these in to compare to the standard Autolite copper plugs that I put in my 2001 2.0L AEG in January of 2009. Here is what has happened so far. 1. Since the new plugs, my idle rpm increased about 50-100 rpm to low 800s to mid 800s . Whether this is good or bad, I don't know. This may consume a small bit more of gas though while sitting at a stop light. 2. Since the new plugs, I can also feel a small vibration that seems to come from the engine bay. This only happens on a cold start as I am accelerating from around 15-40 mph. When it's warmed up, it's gone while accelerating. This may come my new catalytic converter and flex pipe that I just got installed, but I don't know. It may also come from new front rotors and pads that I just put in that haven't had time to properly be bedded, I don't know. I am putting some new dog bone mount inserts in within the next few days as well. 3. Since the new plugs, my engine seems to have had a small performance increase in acceleration, response, and in smoothness; except in cold start accelerations as stated above. This may not make a big deal to some, but I am happy with this. 4. Since the new plugs, the best deal I have had is the lower rpms when I am using cruise control around 40-55 mph. I am serious when I tell you that my rpms went down a good 150-250 rpms at these cruising speeds. I do believe that because of these plugs, I will get a small boost in mpg; I will let you all know shortly. Also note that only the plugs and nothing else was changed at this interval. Can I tell you what happens at 65 mph+, no because I don't go on a highway to school or work. So, my overall impression with the iridium plugs is a positive one so far. I have gone just over 500 miles since the new plugs were put in.
i run 0w30 in my jetta 2.0. fully synth. have for 33,000 miles, no problems, other then better gas mileage
Just changed the oil in my 08 Jetta. went to Advance Auto parts and picked up 6 quarts of Mobile 1 0W 40 and a Fram oil filter.
Textar is the OEM brand..which of course you can get from 1stVWparts.
Last year it was Dunlop Wintersport M3s, which were ok, but not as good as the Semperits
I already have slotted and x-drilled brembo's with pagid blue box all around. I'm in need of replacement since the fronts are warped.
