    Risks of introducing rattles and squeaks with dashboard replacement?

    Without going into too many details now, I was wondering what the consensus is on the risks of replacing a dashboard in a modern car -- namely are you risking introduction of problems like rattles and squeaks. Anecdotal evidence always seems to scream "you'll get lots of rattles!" but it's hard...

    Nissan XOM full synthetic 0w20 for VK56

    I bought my first-ever truck today, a 2021 Nissan Titan Pro-4X. Fully loaded and at a great price with the end-of-year deals and haggling. It's got the trusty VK56VD in it and the manual calls for 0w20 every 5k. This motor was revised for 2017 where they made it direct injection and bumped the...

    2017 Corvette / Motul 300V 0w40 / 6.8k miles

    First full interval on the glorious Motul 300V 0w40 "Trophy". I switched to this stuff after seeing too many UOAs of the M1 Formula ESP 0w40 come back out of grade. It had worked well in my other cars so figured it was worth a shot. Roughly the same number of miles as the previous OCI, and...

    Clutch fluid UOAs?

    Is there any value in having clutch fluid (Super DOT 4) analyzed via UOA? It is not a shared sump with the brakes, but rather, a dedicated system.

    Need a sensible but fun daily

    My Corvette has worked fairly well as an only car for the last 3 years, but I think it's time to finally relegate it to track duty and fun/weekends. Not only does this give me more leeway to run more aggressive tires and potentially modify it further, but it adds a "safety margin" should...

    2017 Corvette / 14.4k / ACDelco MTF

    This is the third manual transmission change the car has seen. Mileage worked out to nearly double (14.4k vs 7.6k) and track time was about 50% longer (22 hours vs 15 hours). The car has a dedicated transmission cooler. Blackstone said things still look fine. Wear metals are dropping on a...

    2017 Corvette / 14.4k / ACDelco 75w90 gear oil

    This is the third rear differential fluid change the car has seen. Mileage worked out to a tad longer (14.4k vs 11k) but overall track time was similar (22 hours vs 24 hours). The car has a dedicated differential cooler. Blackstone highlighted that iron came down even further despite the longer...

    2017 Corvette / Mobil 1 ESP 0w40 / 7.1k miles

    This is the third full interval with the M1 ESP Formula 0w40. I pushed it past my usual 20% OLM reading and let it go down to around 3% which was around 2k extra miles. But this also worked out to a lot of track time: about 15 hours! Several of those track days had ambient temps in the mid-90s...

    TT @ MSR Cresson + HPDE @ ECR

    Performance-oriented Dexron III fluids?

    What are some proven fluids for track/race use in a GM manual transmissions requiring Dexron III? The usual suspect always seems to be Red Line D4 ATF but I'm open to other options. Motul Multi ATF, Schaeffer 204SAT All Trans Supreme, Renewable Lube Bio-SynXtra ATF PLUS, and Amsoil SSS all look...

    Low VI gear oils

    I'm shopping around for 75w90 gear oils for my C7 Corvette and am noticing that many of the well-regarded or track-focused products (Gear 300 LS, Amsoil SVG, Delvac 1, etc.) have very low VIs...usually between 140 and 160. Why are these so low despite being synthetic formulations? By...

    History and development of Motul 300V

    Racer.com, one of my news sites for all things auto racing, had a quick sponsored article about Motul 300V. I had never known where the name came from! (in honor of their 300th victory) <a href="https://racer.com/2019/10/09/special-the-history-and-development-of-motul-300v/"...

    2017 Corvette / Mobil 1 ESP 0w40 / 5.2k mi

    This is the second full interval with the new M1 ESP Formula 0w40 with about the same mileage and duration, but less track time (5 hours this OCI versus 10 on previous OCI). The OLM read 30% when the oil was changed out. Some of these track outings were in ambient temps of 90-100 F, and the PDR...

    Got the Corvette out on track at COTA

    Since I recently moved down to Texas, I now have easy access (~3 hour drive) to Circuit of the Americas! They do rent the track out to various clubs though it's quite a bit more expensive than others. A typical track day there is $495 per day with some minor discounting available for early...

    2017 Corvette / 7.6k / ACDelco MTF

    Here's the latest form my 2017 Corvette Grand Sport's transmission (Tremec TR-6070). GM recommends changing every 15 hours of track use so that's what I did. I might shorten that a bit next time since it's really thinning out, or maybe move to a more stout fluid. Blackstone said they think...

    Bucket list track complete: Road America

    I have spectated various races at Road America for years, but was apprehensive about actually driving on it for a full track day/HPDE. I finally sucked it up took my Corvette out yesterday! What a track...it's extremely fast and definitely has some areas where you have no room for error, but I...

    Fresh footage of my Corvette on-track

    I finally got a GoPro mount that attaches to my harness bar, so I figured it was time to take some in-car footage with an external mic. This is Autobahn Country Club's full/combined circuit. I was able to turn a new personal best despite being on worn-down brake pads and a more sedate Pilot...

    Anyone using Renewable Lube 75w90 for severe duty?

    My Corvette will be due up for a rear differential fluid change pretty soon. GM recommends it every 24 hours of track use. OEM fluid is an 75w90 GL5 LS. I've had my eye on Renewable Lube Bio-SynXtra GL-5 LS but am not seeing many UOAs or info on here for people using it for "severe duty". It...

    Frustrated with lousy spray bottles

    Can someone recommend a quality spray bottle for detailing? I'm getting sick of various brands' bottles developing leaks, handles breaking, or just completely ceasing to spray after a month or two. I'm not even hard on these things -- they just stop working. I understand that everything...
