stock filters can be cought from any automotive shop eg autobarn get ryco as they have an anti drain back valve and have a better filtration system as the webbing inside is 4 times as long as wesfil so better filtering and the r33 on is under $10 i think aslo the nissan ones are made by ryco just stamped nissan as is holden ford and mitsu but they dont tell you that as they want you to think that if your getting a manufactures filter the service is better but this is not the case and yes i do know this for a fact as all those training nights at autobarn werent all for nothing
also royal purple is once again for high reving engines as in being on the track if you dont belive me theo gt autosound also a friend of mine and he uses it in his drag s15 i promiss you dont need that sort of oil for every day driving and a few hills runs now in saying all this if you want to spend money cause it makes you happy or what ever then buy the motul 300v now the most intence race ever would have to lemoun (spelling sorry) the 24hr car race anyway and guess what they use.....yes motul,
now working at autobarn you really need do need to know what your talking about when it comes to oil and performance and ppl that know me know i know what im on about most of the time but if you give someone the wrong oil, verscosety, weight and brand then i could cause them to be sued i also recomend what i use and that goes for workshops and so on so if anyone on sau is using redline pleeeas change it straight away cause i do love you all so and um yeah thats all
