On the subject of oil.
Found an interesting quote on SELOC. Has anyone done anything similar in the scoobs?
<< Oil - Hat eating time......
OK, I am the first to admit, I am always somewhat sceptical when reading claims of product X vs. Y etc etc. I have probably developed an over-enthusiastic nose for snake oil over the years after so many bull**** claims of XY&Z, so you can imagine my thoughts when Simon from Opie oils sent me some stuff comparing engine power outputs between different oils etc?.
He seemed very specific about all this, and, having to do some dyno work anyway, I though ?what have I got to loose?? so I?ll give it a go?.
So, engine filled with 15W50 Silkolene Pro-R Info, made 256.4Bhp
Oil was then dropped, and re-filled with 5W40 Silkolene Pro-S Info, made 262.7Bhp
So, I guess it?s hat eating time for me!
Next test I want to try is with gear oils, and if we get similar results, then that?s approaching 5% power hike (at the wheels) for an oil change?
Thanks go to Simon from Opie for his patience with the eternal sceptic (me!), and for putting in the leg work on this and other lubrication issues I have been struggling with.
Notes:
Engine was fully up to temp, water at 86C and oil at 110C for both tests, each test was benchmarked over 3 runs each, after the engine was loaded for several minutes to bring the oil temp up. BHP numbers refer to power at the flanges on a dynapack chassis dyno, engine was a K20A2. Please note these figures do not relate to anything else as they were done during tests on other parts/mappings etc.
