ATF helps I guess, never really bother with this mod coz I change gear oil every 20K, regardless of manual and warranty definite void if install this now.
I've just used Havoline 10W40 semi with the latest SN rated API converting from Petronas Semi. I also change air filter at same time (10K service interval for that coz by 10K, dirty liao).
So not sure the noticeable vibration coz by changing new air filter or EO. Initially have slight lose of high end power, seems slower in acceleration to reach 110km/h, also noisier just like when I just change LCP.
Anyway after 300 km of driving since then, as of today, engine vibration seems to subside greatly, acceleration somewhow smoothen and engine noise reduced. Had absolutely no idea why it happen, maybe sudden change of a better SN rated lube and new airfilter causing ECU to take some time to familiarize with new changes...(theory only)...will monitor another 200-500km as it seems to be improving daily for now
Added on September 6, 2012, 12:40 pmOil filter when clog, will usually activate bypass mode, meaning no more filteration, all contaminants that flow thru it will go directly to your engine, valve, whatever small holes they could clog themselves in. So it won't tear up no matter how u use it.
Notice you're having Blitz Racing Oil there as well. A note when using Racing Oil, they put the word there for a reason. Racing oil has higher level of anti-wear protection meant for racing than street lube. It comes with ZDDP that will greatly mess up your catalytic convertor....if you don't have it anymore (modded out), then it will poison the air greatly vs normal street lube. Performance addictives definitely more than street lube.
A key note is it also has MUCH LESSER detergent, meaning it will not clean your engine very well and addictives will run out sooner than usual. It will result in dirtier engine and oil way those valves, tiny pathway running the risk of getting clog in long term. So I would not recommend using a racing oil for long term.
alright noted that..
didnt know got different..
