Posted 23/10/06 03:45 AM Share Posted 23/10/06 03:45 AM (edited) Hi guys,Thought I'd post this up and see what you think!I had Valvoline Synpower 5W-40 in my ute and ran up 215 rwkw (down 30rwkw but that's been fixed up now!), it was checked and was running that curve consistently, so it was rolled forward, dumped the oil and oil filter and changed to Belray EXS 0W-40 Superbike oil.It was warmed back up, checked the oil level and ran again pulling out a 226rwkw...That's a 10rwkw gain from oil....And yes it was a change to thinner oil but not by much, especially at running temp.Interesting gain for the dollars huh......Dave(I'll try posting the image right way up!)

XRQTR Member 34 Member For: 19y 4m 2d Posted 23/10/06 08:51 AM Share Posted 23/10/06 08:51 AM Race oils aint all that good in every day start/stop driving.You might want to check your oil quality alot more regularly, these oils are great but if you are using them for a race meeting maybe two, they perform great in those conditions but as I say 'most' do not do well in every day situations. Especially listen out for any engine rattles, I know people that swore by them when they put them in and then a week or two later started to hear engine knocks and rattles.Remember race cars/bikes are almost never under 4500 rpm and that is where these oils are designed to work.

But if you are happy to go with it then as I said before just make sure you check your quality more regularly and be prepared to change it twice as often at the very least, if not more lolAlso not forgetting it's a bike oil so it's peak efficiency is above the rev limit on pretty much most cars, if you still want ot use it at least use one that is designed for car engines.

I decided to try out some of Royal Purple eng oil that seems to be all the rage at the moment and im quite surprised at the difference it made to the cold rattle. The motor used to produce piston noise between aprox 1100 and 1600 under no load. the range has reduced to aprox1300 to 1500 rpm and is barely audible from inside the car,(although it was always pretty hard to hear it over the t56 anyway....) the oil was quite expensive but seems to be doing the trick at the moment. Apparently 10000k's is the recommended interval for the 5w30 with a filter change around 5000k's. So although the oil is basically twice the price of regular oil, the extended interval (i would normally change it at 5000) may mean it works out around the same. I have a clean control sample and i'l be getting another sample done in 5000k's to see how its holding up.... ← Link to comment Share on other sites More sharing options...

The new oil simply brings the power back to what it should be.While power gains can be found by using better oils, the major advantage of a pricier synthetic oil is that it retains it properties for longer, thus retaining the correct power for longer.
