Torqstorm 401 Build

about oil, I was surprised to find euro formula Mobil 1 at our Advance auto store. its one of the best over the counter oils, though its not discounted in the ads. So, I went with high milage Castrol synthetic performance oil. it was $36 while the Mobil 1 performance 0w-20 was $32 there abouts, after discount.

As stated by a previous member about oils, Joe Gibbs does use another company to label their own oil. Though, it is spec is a Joe Gibbs formula not what is sold by original label. Many relabeled products get some additives or changes to the formula to make a product more suited to the needs of the order.

That is why Joe Gibbs oil rates better than the oil its based upon.

there is no reason why a high milage oil wont work, just the additives may not be suited for ones needs, by the fact shorter change cycles will be needed, as the oil has a smaller brake down window over the higher rated oils. Though it is one tuff oil when you need wear protection when you do stress the oil. Probaby a great oil for street use, and some occasional strip use without change outs.

I always used the brake down window as a key indicator to how often I change the oil. Stress the engine, your stressing the oil.

There's an infamous oil blog out there (https://540ratblog.wordpress.com/2013/06/20/motor-oil-wear-test-ranking/) that says the sheering strength is most important regarding wear. The author goes to great lengths testing a variety of oils for many characteristics such as sheering strength and thermal breakdown temperature. The results of those tests indicate to me the Joe Gibbs LS30 is a good choice for this engine's use. My engine builder recommends the use of a break-in oil to seat the rings properly. -Steve-

Wasn't negging your choice oil, just making comment on others that were also top rated. Yes, Mobil 1 has only one oil that meets your criteria, and that's the Euro formula, not the more commonly found oil you selected earlier.

I had the Euro formula rang up, and found it not part of the oil sale this month. It was another $20 on the total

Thats a good looking build. I a looking forward to seeing your Dyno numbers.

Steve,

Amsoil makes an oil specifically for the older hot rods, zddp included.
