    Used GL-5 oil in GL-4 transmission, need advice...

    I'm at 100K miles now with my car; so 30K with the current fill of Redline MT-90 and the shifting is just awful. It takes awhile to get into gear and it feels very notchy in the process. Can I hide this problem somehow with a thicker oil? My tranny requires GL-4 75W-90 per VW. Thanks

    Just finished Auto-Rx, would like some advice

    For the initial cleaning phase I ran M1 0w-40, then for the rinse phase I used normal Pennzoil 5w-30. I just changed back to M1 yesterday and the engine is noisier and not as smooth at idle as compared to the dino oil. The performance is excellent though. Should I put in a different synthetic...

    auto-rx 1st treatment / three vehicles

    I'm in the same boat, I'm just about finished with the cleaning phase, but I don't want to put in a dino oil. I normally wouldn't mind, however, it's winter here and I don't want too much start-up wear and tear (because the dino oil can't flow as well). Can anyone confirm this?

    Used GL-5 oil in GL-4 transmission, need advice...

    I just put in RL MT-90 a week ago and the shifting is tenfold improved. Thanks for the recommendations. Initially though, the first few days, it was very difficult to shift, then one cold day it was possible to shift with relative ease. I guess the fluid had to break in or something.

    Need some help diagnosing 1.8T noise

    It has a timing belt actually. I'll try changing the filter tomorrow. If it is the filter wouldn't I get a low oil pressure signal and a DTC(Diagnostic Trouble Code)? I checked for DTC's, no faults found. I tried to reproduce the engine knocks under similiar conditions today, but they didn't...

    Need some help diagnosing 1.8T noise

    If the TB tensioner was bad wouldn't it be noticeable throughout the operating range of the engine? Plus I changed it 20K ago.

    Need some help diagnosing 1.8T noise

    I just ran an application of Berrymans in my last tank full. Maybe it dislodged something and it lodged in the injector. I'd say the sound was half way between sharp and dull. Thanks

    Need some help diagnosing 1.8T noise

    Keep in mind this is a really sporadic occurence. I've started the engine warm a lot without this happening. Rickey, I like your leaking fuel injector theory. Does the frequency of this occurence support it? I am already using premium BTW. Would the temperatures get that high at startup? I'm...

    Need some help diagnosing 1.8T noise

    The filter is located on the bottom of the engine. So wouldn't gravity prevent the oil from draining back? The filter is Mann. Thanks. Oil was changed about 1K ago.

    Need some help diagnosing 1.8T noise

    My engine has only done this twice, but two times too much. When I start the engine, it makes about four knocking sounds in 1-2 seconds. Like: ta-ta-ta-ta. It occurs when the engine is warm. As I said, it has only happened twice, but most recently today and it has me worried. The oil level is...

    Bleeding brakes - just another reason to do it

    Looks like I'll be doing this soon. I have never bleed the brakes. The dealership(s) insist that it's a "lifetime" fill and they only have to top it off at every service. They said they same thing about my coolant and gear oil.

    Used GL-5 oil in GL-4 transmission, need advice...

    gtx510, Yeah, I'm in Germany. I didn't even occur to me to look at the "local" market given the usually high prices. I already ordered Redline MT-90. I'll try one of those Liqui-Molys if I don't like the Redline's performance. Mechtech2, When I shift I have to wait half a second for the gear...

    Used GL-5 oil in GL-4 transmission, need advice...

    unDummy, I had the GL5 in there for 75000 miles, under really strenuous conditions at times. Bobert, I agree, this stuff should act as a nice quality flush.

    Is there a point to use AutoRx with 5000 mi OCI's?

    I have used Mobil1 0W-30/40 for the lifetime of my car. My OCI's w/ filter are 5K mi. This car sees extended runs (30 - 90 mins) of speeds in excess of 100mph on a regular basis. The car runs pretty well (26 - 35 mpg). The compression doesn't seem too good though: 185-175-165-180. Do you...

    Used GL-5 oil in GL-4 transmission, need advice...

    That sounds good, but what do you think about running Auto-Rx to clean it out?

    Used GL-5 oil in GL-4 transmission, need advice...

    Is there anything I should do to clean out the GL-5 stuff first? Or run something that can "recondition" the gears, before putting in the new oil?

    Not only the tranny, just about every part of the car.
