Mixing oils for additive benefits????

[SSLNF]

I've been reading these forums for a while...especially voa's on different brands of oils.

Is anyone purposely mixing oils to achieve an additive compound they like? Was thinking of mixing PP w/ RL (3 to 2 ratio). I like the nature of each of those oils in the 5w30. Anyone else doing this?

I have a DI turbocharged engine putting running 22-26psi (depending on which tune I run) and run the car at the drag strip and track events (atleast once a month it seems). The engine in max performance puts out 342fwhp/413fwtrq. My daily driver mode its still over 300whp, but much lower torque numbers (318).

Although you'll hear that it's not a good idea, many people have blended diff brands of oil for a long time with no problems.

Having said that, I'm not sure I'd make my own blend for a high hp turbo application. I'd prolly use the 5W-40 RL for your application.

You can call RL and talk to them directly about this, they will know why you should/shouldn't do it. Their phone # is (800) 624-7958

WELCOME TO BITOG.

The search function is pretty hard to use, but this has been discussed. There are pro's and con's to mixing oils. While one oil might be strengthened another is weakened, and the add packs are thrown off some people believe.

If I were you I think I'd just use the RL and not dilute it for "your" application. BTW PP is a great oil by itself. JMO

If you aregoing to buy a nice synthetic like RL you will for the most part be (in general) diluting most of the additives by adding PP. Not that PP is not a good oil but for your turbo and stated use go with the pure RL. OR look into the easily found syn HDEOs (Rotella, Mobil 1 Turbo Diesel Truck, Delvac 1, Delo etc) or Mobil 1 0w40/GC.

Unless you are an oil engineer don't do it. No reason to. Just pick a good oil and use it.

Mixing oils won't hurt,ut then won't help. what happens is you will be diluting the [srtonger] oil.

The only safe blend I've found was adding 500-750ml of M1 R 4T, the most additised mobil oil for sparkers, to any of the mostly PAO M1 PCMoils to make a super oil. It also worked well on top of Valvoline synpower.

I was doing some pipe threading yesterday. I have always assumed the thread cutting oil is laced with extreme pressure additives. It has a terrible sulfur compound smell. Would it give the flat tappets in my truck more protection if I added a little to the M1?

If you feel the unquenchable desire to tinker with your motor oil formulations there are a few break in additives that will crank up the zddp levels as high as you want, then there is Lubro Moly MoS2 if you are a moly freak.

Gear oil in an engine = see you later copper!

generaly speaking i don't recommend it,however,it can be done if you take in some factors for which you need to have some accurate information.

what i look for is a similarity in base oils and certain like-ness in elements used in the add-pack.

for example,some oils are really high in Ca and low(or almost nil) in Mg and others are lower in CA but higher in Mg. on this,i would only mix like with like so as not to throw off the balance and possibly effect the purpose of other elements.

same thing with the base oils.it does you no good to change the balance of a PAO/ester oil by adding a different or lesser base oil. generally,i think like with like will give no problems.

usually mixing is done to increase certain elements in the oil,like Ph and Zn or maybe even raise a base stock that's already in both oils...and usually by only adding one or two qrt/L.

it may be best to get information from the formulator to see if there's a specific reason why a particular oil can't be mixed.(and i don't mean the usual rhetoric they give)

if you have a fairly new vehicle though,i don't see any advantage to this....just choose the right oil for your purpose or one that has been proven to work well.

the only temptation I have is to toss a little Super Fine grade MoS2 powder in with my SSO.
