    Viscosity levels

    As I am an Algebra teacher, lets do a math lesson.
    1. There are four quarts in a gallon.
    2. Four times 10/30 plus two 60s equal 160.
    3. Divide 160 by 6= 26.66

    Overall viscosity 26.66/40.

    I believe that in too thick for an LSX series engine.
    I hopes Sarge chimes in on this one.

    Awaiting sarge. It cured my issues so im sticking with it. Every engine is different.

    I might try something else next time Just for kicks

    Well couple of issues you need to consider when mixing.
    Firstly when you mix two different "brands" you may be in reality canceling out one brands add packs with the others add packs. Add packs are designed by the blenders to work together and provide you with anti wear,suspension,anti foaming,detergents, friction modifiers etc. These are chemicals that all walk a very fine line to begin with.....One manufacturer (or blender) may use Zinc dithiophosphates, organic phosphates, acid phosphates, organic sulfur and chlorine compounds, sulfurized fats, sulfides and disulfides for his anti wear.....the other brand may use a totally different chemical makeup like sodium, moly etc. etc. What happens when you mix is Brand A will totally counter act Brand B add packs. You get high wear all of a sudden. You don't know this is going on and you think all is good....until you spin a bearing and find out you engine has been eating itself because you are a home grown oil blender that don't know diddly about add packs. Dangerous place to be. I always recommend if you are blending do it only for HT/HS ( High Temp High Shear) viscosity adjustments and utilize the same blender when doing so.....in other words blend Pennzoil Platinum 10-30 with Pennzoil Platinum 20-50.....this way you are utilizing the same manufacturers add packs and not destroying the already fragile add pack chemistry.
    With that said...let's talk blending for HT/HS.....which I do by the way.....And for the record I go for the HT/HS number more so than "viscosity" as HT/HS numbers have more meaning to me than what gravitational characteristics an oil has at some temperature. As a motor ages ...yes it loosens up...clearances are larger due to wear....folks have known for years if you utilize a heavier viscosity oil a higher mileage engine will run "smoother"....this is also true for rebuilt motors/high performance engines that will also have more bearing clearance than say a factory spec stock motor......Many knuckleheads use a Lucas Oil Stabilizer to achieve this "smoothness"...or some other snake oil that is nothing more than a oil thickener.....let me sidebar for a second here on Lucas and pick on that POS oil additive specifically.....
    here is the Virgin Analysis of Lucas Oil Stabilizer....
    TBN - 0.1
    Visc - 615.3
    FP - 435
    Calcium - 3
    Magnesium - 1
    Phosphorus - 4
    Zinc - 2
    As you can see it has absolutely no value outside of just being a straight oil thickner. Yes that sez 615.3 Viscosity....so if you use it per Lucas instructions you have close to a 140w gear oil in your motor. Sure your motor is running quieter and smoother...you bet it is....and it is not lubricating worth a damn at that viscosity as the oil is not able to properly access tighter bearing clearance spaces.....but your motor sure is quieter! Or that "tick" is gone.....sure it is...you have pancake syrup in your motor....I digress but I had to show the VOA of that garbage product......
    So if you have a higher mileage motor/high performance/Modified bottom end etc. in the LSX family you should be looking for a HT/HS of 3.2-3.8. So for my exercise I use Shaeefers Series 7000 as my host oil and I will have a target of 3.7 for my Stroker motor based on my bearing clearance of a couple of thousandths versus a factory spec of one thousandths....also I have higher bearing pressure and need a stronger film without sacrificing the lubrication capabilities....
    Now for our resident math teacher ( thank you for teaching math to our kids by the way).....A fella could utilize a blended average.....
    Shaeffers 10-30 has a HT/HS of 3.16 and the Shaeffers 20-50 has a HT/HS of 5.31.
    So I have a 8 quart sump. To reach my target HT/HS using the blended average approach I could assume the following formula to reach my target...
    3.16+3.16+3.16+3.16+3.16+3.16+5.31+5.31=29.58/8=3.69
    Real world problem utilizing this method is viscosity of the mix is more biased toward the thinner oil than the weighted average predicts. Assume that the mixing laws for HTHS viscosity are the same as they are for kinematic viscosity. This means I would be thinner than I want to be. So with kinematic viscosity laws applied some propeller head made us a viscosity calculator with the laws applied in the background and saves us all brain cells and pencils. Thank you geek man.... http://www.gesilicones.com/gesilwiza...ng/fluid2.html
    So now you can plug in your HT/HS numbers and it will calculate the HT/HS for you with the kinematic laws applied. So using my same numbers as before the calculator tells me I need a 70% 10-30 and 30% 20-50 to reach my 3.7 versus the weighted average of 75%-25%.
    So to summarize....
    Thicker HT/HS is good for "non stock motors" and higher mileage motors...usually...
    Use the same blender/manufacturer/brand for your mixing.
    The heavier oil will be more biased to the lower viscosity than your weighted average. So adjust. Cheat with the calculator I provided you above.
    Lucas Oil Stabilizer is worthless shit.
    And for the record my mix is a 12.5-35 weight oil

    I know about add packs because I read all of your crap BUT didnt know they cancelled each other out by simple switching brands(never read it). Only two kinds of PP here. 5w30 and 10w30. I dont want to drive like 50 miles just to buy crap to change my oil, as for the engine it falls in your thicker oil catagory at 157k "stock" engine.Hell I even looked for new castrol edge and couldnt find it. Most people dont wear shoes around here much less know anything about an ls1. Not oprah for sure. Im also not hanging out with people like the Loctite patent owner .. LOL

    Hell I would use Pennzoil Yellow Bottle conventional Josh....like 4 quarts 5-30 and two quarts 20-50 and be a happy camper. I guarantee your engine will appreciate that soup for up to 5K OCI's.
    All my "crap"? I'll kick your ass......LOL..

    LOL...Oprah is my Stroker fed GTO. We call her that because she is fat/black and worth a lot of money.
    He is from Kentucky and the shoe comment is about those he lives around.
    And in final Josh is saying he doesn't hang out with the same crowd I run with.

    OK Now I got it, I think
