It turns 10w-30 into what's known as motor honey
Why do you think you need more zinc? Do you have a flat tappet pushrod engine with a 9,000 rpm redline??? If not, then you really don't need anymore zinc.
Yes, you can use it to boost your zinc and phosphorous anti-wear agents.
Thanks guys. I was just curious. I was considering a synthetic oil and if they have enough zinc in them.
Actually, I run Havoline 20w50 SL in my modified Pontiac 400. I just got off the Havoline Web page it stated that this oil has 0.103 zinc in it. Is this amount suffient if I stick with a conventional oil.
I've switched between Delo 15w40 and the Havoline 20w50 a several times and my motor seemed to run better and smoother on the Havoline.
I ran Royal Purple 15w40 for a short time. With the Royal Purple my motor was very quiet and smooth. However what spooked me was the way it thinned down. Maybe it was just in my head. I'm sorry, I'm off the subject.

There are better products than STP for boosting zddp.
The EOS is around 6000 ppm zinc and phosphorus so you would not need much (ounces) to boost zddp.
STP will thicken unless you can get some of the discontinued STP 6000-Mile Oil Extender.
Big Lots is selling CD-2 Street Legal High Performance Oil Boost (15 oz pink bottle) for $1.99. It has around 4500 ppm zinc and phosphorus and so half a bottle would be a pretty good boost. It is thicker but not nearly as much as STP and so should not appreciably thicken your oil.
There also is a product that some Walmarts carry called Powerservice Diesel Lube Oil Extender. There is a VOA on this site. I think around 3500 ppm zinc and phosphorus and not thick.

You might want to look into SX-UP from Specialty Formulations (a BITOG site sponsor).

The new "STP Racers Edge" product that comes in a quart sized container is much thinner then previous products. I think if anything this new product might be the best choice of a low cost additive available OTC. I think it runs $5.99 at Walmart.
If you want a really well designed additive that is not going to thicken your oil check out "SX-UP".

Good point JohnBrowning. I forgot that SX-UP is not thick, and certainly is a premium quality product.
You'll need to order it. Unless I missed something, there are no retail outlets.
Dont be afraid to order its all top quality stuff.
I'm going to ordering a nice load for the 3 rangers in the family now...
That being said if you are worried about thickening
with something else use 15w40 and with the additive.. you got your 20w50
