Oil type for Kcode

Postby 64.5 07K » Sat Sep 20, 2014 12:57 pm

What available(?) API should a person use to give the Kcode/solid lifters the needed lubrication? Or can a person use a modern hiperf oil with an additive? I do have 16 qts of Q-State SAE 30 HD wt w/API SH, SG; would that give the necessary lubrication? As well, I have 8 qts
of Valvoline Super HPO SAE 30 wt w/API SF, SE/CC....would that work?

Thank you for any help!

I've been using 20w50 racing oil for years and everything is fine. change the oil every 12 months. I think the most important thing is get an oil that contains zinc to help protect the camshaft.

For over 16 years I've been using Mobil1 15w-50 in my GT350's (K code engines) and current current K code as well. Over the last 16 years I estimate that would total to be about 175,000 miles all k code engines combined. Not only did I have zero oil related issues, but every time I had the opportunity to check engine clearances,there was zero wear. These engines were not babied. They all saw 6,000 rpm every chance I had, some of them were sporting vintage Paxton's as well, adding to the stress and the fun.

I cannot emphasize enought the dependability I enjoyed over the years using this oil.

Whatever oil you choose, it should have a minimum of 1200 ppm zinc . If it does not, you will need a zinc/phosphorus additive. The best one I have found is CamShield:

http://www.cam-shield.com

However, there are numerous oils that do have sufficient level of zinc & phosphorus so no additive is needed, the Mobil 1 15w-50 is one of them. A little research in this area goes a long way.

I've used Pennzoil and Quaker State in my cars since 1963. When these cars were first built almost any oil 20W or better worked, 40W in the desert. Currently 20W50 is my choice with a 4 oz bottle of ZDDPlus, the Zinc additive. Following the old "bird in hand" adage, 30W is fine. Avoid the synthetic oils unless you are racing and have a lot of money. In California we have corn "squeezeings" in our gas which is also a problem. Fred (C6ZZKGT) rebuilds fuel pumps with a better rubber diaphragm (at least he used to). Check with him on that.

I'd love to hear the rationale for this statement . Synthetic oils provide a friction reduction that conventional oils will never be able to duplicate. Less friction is directly proportional to less engine wear. And the cost is reasonable. I can buy 5 quarts of Mobil 1 15w-50 for $25.00 at Wal-Mart , granted not my favorite place to shop, but there it is.

In regards to the ethanol (E10), after many years in the vintage motorcycle business I can offer this observation. If you go thru a tank of gas in less than 2 months, you will have no issues with E10 ethanol. If you leave gas in the tank longer than that , you will certainly have separation issues. Not a problem for fuel injected cars so much. But carburetor fuel systems are less tolerant .

Since I have the above noted Q-State and Valvoline 30 wt oils w/the noted API ratings, how do I find out the zinc/phosphorus content is at an adequite level or must I employ the additive? Thanks all for the input!

I would try the manufactures web page first. Most oils these days top off at 800 ppm zinc/phosphorus . A little Googling might also get you the data you are wanting.

I am still doing them and I am currently in the middle of my fourteenth run. I have done over 800 pumps so far.

VR1 has a balanced additive package that is ok on the street. I have seen postings that state not all racing oils are equal and some 'racing oils' do not have the detergents and additives for what would be a normal street car. Our Kars probably would not fall into the category of normal street, but I would stick with the VR1 or regular oil with one of the ZDDP additives.

VR-1 is not really a true racing oil. I use the 10w-30 VR-1 Synthetic. Very good oil with ZDDP additives.

Dear all,

Sorry, I live in France and I've tried to find out.

Is it the oil you recommand : http://www.norauto.fr/produit/huile-2-r ... 37309.html

In France, it seems to be an oil for motorcycle engines.

Thanks for your feedback.

The one that you are showing is not what you need. I did not look up the Mobil equivalent as I use Valvoline VR1 Racing oil in my Hipos:

https://valvoline.com/products/consumer ... otor-oil/6

I have no issues with the Mobil equivalent, I just do not use it.

Not sure who you are addressing this to, but since I had mentioned Mobil 1 15-50', here is the company web page:

http://www.mobiloil.com/USA-English/Mot ... 5W-50.aspx

However, the Mobil1 4T motorcycle oil would work, it's probably more expensive though.

Thanks,

Z-Ray, yes, I was refering to your post.

This reference is not available for cars in France, I could only found it for motorcycle, hence my question.

Thanks for feedback,

Too bad.

But the motorcye oil has even more of the zinc / phosphorus compound (zddp) than the Mobil 1 oil I referenced. I would not hesitant to use it if it were more affordable over here.

If not too pricy, the Mobil 1 4T motorcycle oil would a good alternative for you.

Ole 64.5 07K had the first "treatment" of 30 wt VR1 and has 700+ miles of trouble free operation to Flagstaff, Az., sadly to the Route 66 Car Club's last 400+ car show where they had the old section of Flagstaff closed down for the show,
and return to Tucson.

I used to use Mobil 1 and then racing oils and then use additives. Now I just use Brad Penn Grade One Oil. It is for flat tappet engines and has enough zinc and phosphorus already in it. It is a semi synthetic oil and is recommended by many cam manufactures. I was told by a cam manufacturer not to use full synthetic for flat tappet cams because it doesn't promote lifter rotation. It comes in many viscosities. I use 10 - 40. I buy it at a local parts store and it is available on line. No more additives and no more checking which viscosity has enough Zinc, etc. End of problem for me. I know that European oil specs. are completely different (better) than US oils so it would be different in Europe. Tom

I've got about 100,000 miles, hard miles, on various K code engined cars since 1998 using nothing but full synthetic oil. One would think if my lifters weren't rotating that I'd have SOME wear. But I don't have lifter wear, piston clearances don't change, cams don't go flat, crank and main bearings look new. The suckers just keep going.

Not saying you weren't told this, I'm sure you were. However there is no truth to that statement, it's part of the big myth that, "synthetic oil ... Is so slippery that _________(fill In the blank). The only thing that fits in the blank is that synthetic oil reduces friction, and therefore wear, better than conventional oil. Which is really the only good reason for using it.

This comes under the heading of "the sky is falling", or "synthetic oil won't let new rings seat" (funny, since many new cars come from the factory with synthetic oil), or synthetic oil causes leaks, etc. basically just 100% BS.

This stuff is great...and Expensive! I use it because, well, I do not use a bunch of it, and my engine builder requires its' use for his warranty! Just another possibility for you guys.

If your engine builder requires it for your warranty then that is a really good reason.

I was wondering if there were anymore thoughts on the engine oil question. It's been almost a year since the last post. I have heard that some people are using the Quaker State Defy High Mileage oil. It seems like a good compromise since it is a synthetic blend with over 1000ppm of zinc and phosphorous each. (I forgot the actual numbers) However, in general I find that most of the guys I talk to use the Valvoline VR1 conventional oil. But the synthetics have a lot of advantages, so a synthetic with plenty of zinc and phosphorous for the flat tappets would be a perfect oil. Any new thoughts?
