Zinc Additives, Cam Shaft Or Rocker Wear, And Mileage - A Poll

[siteunseen]

Advance Auto's coupon code won't work on oil so I'm paying $5.99. Every now and again they have it for $2.50, I'll buy a tanker full next time. NAPA closed a brand new building in my small town. More profit in the real estate I reckon.

For fans of Valvoline VR1, it is currently on sale at NAPA for 4.49 per quart, a very good price.

 

All weights, and price is good until the end of April.

(I went with the heavier weight for my trip & summer)

That's cheap, in general, for any oil.  Hope it's not a discontinued product price.  Thanks for the tip.

Bought six quarts of 10W-30.  For a future break-in.

Good deal Zed, I am going back for another case of 6.

 

Trying to catch up with Diseazd's inventory...

Thanks for the info. I hope to stock up. Amazon's price is $5.58/quart. 

 

I noticed the NAPAs in Colorado are much larger than the ones in Georgia.

Valvoline VR1 is a bit hard to find up here. So is Brad Penn But Driven oil by Joe Gibbs Racing is readily available. And they have specific formulations tailored to various engine typed. Its expensive but well worth it IMHO. And you can get the JGR oils in conventional, Synthetic blend and full synthetic.

 

Lots of oil manufacturers making these " niche " oils these days, particularly for older flat tappet engines.

Pennziol GT Performance Racing Oil 25W-50.  Highest zinc of any available engine oil at 1,968 PPM.  Our oil analysis reports zinc levels over 2,100 PPM and its all we use in air cooled Porsche engines.

Agree with that 100% Air Cooled engines are very hard on oils. HTHS properties are very important in all air cooled engines. One reason why the bike guys like Rotella T6 5w-40 Synthetic so much. VW/Audi 4 and 5 cylinder Turbo engines work well with it also ( T6 5w-40 )

 

Of course you have to match the viscosity to the bearing clearances and other design tolerances.
