Anyone know anything about this oil? Specifically the 10W30 Race oil which their site notes conforms to API class SM standards. It is a PAO/Group III. Ya know like Mobil 1 use to be before it got greedy? Looking for VOA and first hand knowledge.

Found this UOA for this oil just minutes after posting the original on BITOG. Would love to see a VOA on it.

Found this VOA of Pennzoil Ultra Platinum 5W30 to compare additive packages to the Idemitsu Race 10W30. 

 There a darn few PAO's on the market and this is one of them so it has my current attention.

 

When someone tags an oil 'Race' normally we know it doesn't have enough acid package and too much wear package.

This does not seem the case. Although no base number is given for the Race oil I'd bet dollars to donuts it more than suitable for street use. Idemitsu has a level of moly I've only seen in Red Line HP and yet the wear additives capable of cat damage are very workable. Makes this a choice to be considered for motors that use some oil and yet the owner would like to benefit from a PAO base oil.

If anyone has some experience with this oil in something other than a Wankle Rotary I'd love to hear it. 

I've found sources on line for under $9 a quart.

On page two of this products SDS I took note of the 60-70% PAO blended with 10-15% 'mixed' mineral oil base stocks. I also note they are solvent dewaxed paraffinic. That's a Group 2 and I hear a gasp in the room. Junk you say??

 

ALL DEXOS1Gen2 oils contain about the same amount or more of this material for the purpose of 1.) suppressing the aniline point enough to keep the 15% additive package in suspension. And  2.) The Dexos1Gen2 license does not allow and ester or a PAG to be used as a base oil.

What a great read.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
