    Factory fill 5w30, 1,395 Miles, 2017 Chevrolet SS

    I just did my first oil change in my new 2017 SS. Based on advice from some of the powertrain engineering hardware engineers at work I targeted the first change to be 1,500 miles assuming it should be nearly fully broken in at that point. A 900 mile weekend trip forced me to change it a little...

    M1 0W-40, 6,205 Miles, 2012 VW GTI 2.0L TSI

    <img src="http://i58.tinypic.com/1z3tn5z.jpg" class="post-image" alt="" /> I know that the OE recommended interval is 10,000 miles on VW 502 spec oil. But I also know that VW also included 30,000 mile free maintenance, so I'm skeptical if the 10,000 mile interval was to save money on the...

    M1 OW-40 + M1 HM 10W-40

    My search for a good yet affordable oil for my new 3.8 in my SC is still on. I'm really leaning away from diesel oils because of all the detergents. My engine just doesn't need all that detergent and I believe their is a reason very high performance oils don't have gobs of detergent. I'm...

    Oil suggestions for new engine in my SC?

    I just picked up my 1990 Thunderbird SC from Super Coupes Unlimited where it got a full engine rebuild. Mostly stock parts except 94 spec connecting rods with Wiseco forged pistons. The stock oil spec is 5w30, but my rebuilder told me he set the engine clearances for a 40 weight. It has a brand...

    Schaeffers 9000 5w40 in supercharged 3.8L?

    Currently my supercharged 1990 3.8L Thunderbird is running 5w30 Pennzoil YB for the winter. It's going to be due for a change probably in the spring. The summer racing season starts in April, the car is modified and runs 14 second 1/4 miles. I live in southern Michigan. I was considering running...

    Used oil analysis finding coolant?

    I've noticed some milky substance on my oil fill cap and a thin layer of milky substance on the end of my dip stick. This is making me question my head gaskets. I'm thinking about changing my oil now and send some into blackstone. Will blackstone be able to tell if its actually coolant in the...

    Motorcraft 5w-20 or Maxlife 5w-20 for 4.6L F-150

    My mother's 97 Ford F150 with the 4.6L V8 is up for an oil change in a week or so. Up until now we have been running Maxlife 5w-30 in it and it seems all is well. It has about 106k miles and burns around a quart every 3000 miles. This engine has been back-specd for 5w-20. Considering this, and...

    Oil cooler exchanges heat with coolant

    I just thought I'd bring this up on here for discussion purposes. My 1990 Thunderbird Super Coupe has a factory oil cooler than runs engine coolant through a stacked plate design on the oil filter mount. I was curious on everyone's opinion on here what this does to oil temps. The car uses a 195F...

    Interested in German Castrol

    I am suddenly very intrigued with GC and I am trying to compare it to what my current choice was, ML Full Syn. The 100C cSt is 12.1 vs 11.7 of the ML. But I do not like how Castrol's PDS is set up. What is the 40C cSt? Is it 66.8? How is the additive package in the GC? Obviously its very durable...

    Pennzoil YB, New formula?

    After reading, it seems Pennzoil YB is regarded as one of the best dino oils. From what I've read, it seems the formula has changed recently, shown with a lot more Boron. Is the new formula still as good as it was before?

    Oil Suggestions for 1990 Thunderbird Super Coupe

    I have a 1990 Thunderbird Super Coupe that just rolled over to 100,000 miles a few weeks ago. It is a supercharged Ford 3.8L V6, running 15 PSI boost. I'll be due for an oil change in a few weeks, I'm currently debating between Maxlife Synthetic 5W-30 and Penzoil Platinum 5W-30. Price isn't...
