Klotz - BEST PERFORMING FUEL & OIL FOR CRATES!
Below is information published by Hendren Racing Engines. Owner Steve Hendren has spent hundreds to thousands of hours testing 604 Crate engines and finding the best products to use on and in your 604 Crate. Klotz Oil outperformed other oils being used in crate engines.
Call me today! I have on hand the Klotz KE-940 10W-40 Oil that outperformed the top-rated Schaeffer Oil by 3 HP and 4 ft/lbs of torque! Klotz Crate Fuel is also available!
402-750-4734
Other weights of oil and octanes of fuel available as well.
The following information was provided by Hendren Racing Engines after testing multiple brands of oils in 604 Crate engines:
Our baseline oil was 10w/30 Mobil 1 Synthetic, purchased at the local auto parts store down the road. Every oil in this test is being compared to our baseline oil, which is commonly used by many Crate racers. Our testing was simply oil against oil, using the same 604 GM crate engine on our Dynojet Chassis Dyno. We were strictly looking for horsepower and torque numbers, and not at wear or protection characteristics. We would like to state clearly that every scientific test has its limitations. We did everything humanly possible to ensure our results were as accurate as possible. We are not, however, claiming that these results are 100% accurate to the extent that they could be replicated in a laboratory environment. Oils were tested in the following manner: we would run, empty, change filter, and fill the engine with the next engine oil for each test. With this manner, we knew that there could be an ounce or two of the previous engine oil in the engine, but without testing on a dry sump engine with a scavenge system, this is as close as we think we will get to accurate results. In addition, we tested all of these oils on the same day so that temperature and humidity would be as closely matched as possible, but even the slightest change in each of these factors can introduce a margin of error. However, all testing fell within the dyno's correction factor.
These results are specific to a 604 crate engine, and not a super late model or limited engine. Engines running tighter clearances, using solid lifters, etc., may see different results than our testing shows.
Our conclusions: We feel that each of the racing oils that we tested are high quality engine oils and will protect your engine. If a few horsepower and a few foot pounds of torque are worth it to you to change oil brands, then that is up to you entirely. When we look at these oils, we don't simply look at the peak horse power and torque numbers. We look at the entire RPM range and the effects that a particular oil may have on the engine. Keep this in mind as you view our results. We would not hesitate to recommend the use of any of these oils to our customers, or to the racing public as a whole. We are posting the following dyno graphs for you to look at and draw your own conclusions. When viewing these graphs, we recommend that you pay attention to the numbers from 3,500 rpm on up. Due to the nature of the chassis dyno and the fact that a human is actually in the car using the gas pedal, numbers below 3,500 rpm could vary a bit and give you a false reading.
Update: After this initial round of oil testing, Hendren Racing Engines worked directly with Klotz Lubricants to develop an oil specifically for Crates. The Klotz KE-940 10W-40 Oil outperformed the top-rated Schaeffer Oil by 3 HP and 4 ft/lbs of torque!
