How does Schaeffer oil compares to other brands? This is the question many have when they are told about Schaeffer motor oils and their success stories. I was skeptical until I tried them for myself many years ago and have been a fan ever since like many. Take a look at these results after testing many, so called, good competing oils against Schaeffer's 7000 synthetic plus oil. You'll be amazed and want to try Schaeffer oil for yourself. I can guarantee you will not be disappointed.

We have concluded our first round of oil testing. Sorry for the delay in getting this information out to our customers and followers, but our first attempt at testing resulted in electrical issues and transmission issues with the test car. It took several days to resolve the issues, which put us way behind on completing this round of testing.
Please note that the bulk of our testing was preformed on one day, January 20th, 2014, with oils provided by five different oil manufacturers. 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 horse power and torque number, 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 3,500rpm 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 3,500rpm could vary a bit and give you a false reading.
**NOTE** In our initial testing on the day that we had to stop due to electrical issues and transmission issues with the test car, we also tested Amsoil OEM 5w/20. On this day it actually out produced the Mobil 1 baseline and the Amsoil RD30 by a significant amount. Unfortunately we did not have more of the OEM 5w/20 to test with the other 8 oil’s on 01/20/14.
**NOTE** Our baseline oil test was conducted before other oil’s were tested, and then again after all other oil’s were tested. You will notice in the first graph that our baseline oil performed almost identically at the beginning of the day and at the end of the day. This fact gave us the confidence that our testing was very accurate throughout the day.
