Following on from some on-line chatter regarding which oil viscosity best suited a particular engine in relation to power, we were curious too so decided to undertake some testing in order to have certainty on this matter.
The test results certainly surprised us and dispelled some myths and assumptions.
The test method used our Rototest chassis dyno which is accurate to <1%, measurement repeatability to <0.05%, zero tyre/grip/camber/toe interference, correcting to DIN 70 020 making the data sets entirely representative.
We wanted to ensure testing parity between the oils so endeavored to equalise the oil temperature to an operating window of 75-76 degrees, engine coolant temperature window of 90-95 degrees, taking 6 test runs then taking the average power (not peak power) of the runs in order to gather accurate and representative data.
Note that we were exclusively looking for the impact on engine output, not engine life/wear or temperatures etc, and that the testing is confined to HKS, Millers, Joe Gibbs and a cheap “off the shelf” Carlube oils. There are many other brands of oils that may perform better, worse or similarly.
Out of interest we also tested ZX1 oil additive which claims to be the ultimate friction eliminator, to assess it’s impact on performance.
The methods and results are shown on the linked attachment. Oil Testing – Analysis
- Whilst it may seem intuitive to assume that higher viscosity oils will reduce engine output due to higher parasitic losses, that actually isn’t the case among the oils tested.
- Price isn’t always the determinant of performance among the oils tested, although it may have other beneficial attributes.
- There is a significant variation on cooling effectiveness between the oils.
- ZX1 is effective by yielding approximately 2% more power.
The Institute of the Motor Industry (IMI) has just approved Advanced Engine Management Systems Calibration, which is the latest short training course to be provided by the Academy of Motorsport Sciences.
The IMI has thousands of professional register members who are compelled to undergo Continual Professional Development (CPD) programmes in order to retain their IMI membership.
Details of the Advanced Engine Management System Calibration course, and the other courses can be seen here.

Known for it’s range of very high level stand-alone and “plug & play” ECU solutions, we are very pleased to welcome Syvecs on board as a technical partner.
Torque Developments International has supplied, installed and calibrated many successful racing applications with Syvecs powertrain control systems. Please let us know if you would to discuss a project or learn more about training.
Buoyed with confidence from having years of successful race winning ECU mapping services under our belt, we decided to make things a little easier for you to chose us as your preferred service provider by eliminating any risk that we won’t do a great job for you.
Here’s the deal; if we remap your ECU and it’s subsequently discovered that another firm has improved upon our work, we will refund the money you paid plus the cost of the fuel used*.
Another interesting thing we’ve noticed recently is that although our charge out rate is relatively higher than some of our competitors, because our equipment and processes are very efficient, the overall cost of the services is often cheaper than our peers.
Please give us a try. We’re confident that you won’t be disappointed, but even if you are at least it won’t have cost you anything!
*The “small print”:
- A claim must be made within 1 month in order to eliminate any adverse effects due to wear and tear.
- The specification of the car must not have changed in any way.
- A claim must be validated on our Rototest dyno (you can appoint your own operator if necessary)
Please review this page for information on our ecu mapping services
We’ve recently invested in training and new equipment to improve our manufacturing and fabrication capabilities.
First in line to benefit from these facilities are a new range of exhaust manifolds which have special internal aerodynamic features as well as benefitting from our pulse tuning expertise. What this space!
We can now undertake most types of alloy and stainless fabrication and welding processes, so please let us know if you have any requirements.
