Oil Change And Maintenance

Got my excellent oil filter and oil the other day. The Knight Sports Oil Filter I purchased over from Corksport (they have all of Knight Sports catalog, just not posted on the internet) which is apparently a high quality racing oil filter that is strictly for rotary engines. If you look in the picture below, the size compared to OEM is a huge difference.The oil filter is specially designed to work with premixture oils and synthetic oils, as opposed to the old 5 w20 that Mazda recommends. The oil is a 10 w40 Synthetic oil by RedLine and is some of the highest quality stuff you will find on the market right now. I was very hesitant to even go synthetic at first, but after reading various reviews on the rx8club.com boards, I had heard numerous good things, especially with a higher number like 10w 40.

My understanding is that the way RedLine oil is made, it has certain properties about it that make it so the apex seals wear and tear much less then normal. And since the viscosity is higher in the oil , as the oil heats up and thins out, it won't be thin to the point that seals could start rubbing against the housing, making this oil one of the best choices. Granted, most tuning companies in Japan are running their own premixture oils of 10w 50, but this will do for now.

I just want to add that after changing my oil and oil filter to this, my engine feels a lot happier and more at home when revving. Before it felt great, peppy and lively, but a slight bit "upset" with small rumbling. Now, when revving the engine, it feels smooth as butter, and I already noticed a slight increase of MPG. Idling is still similar to before as I have done the airbox modification, but it was still noticibly better, by both me and the mechanic. I highly recommend this oil and oil filter to anyone who is serious about maintaning their RX8 to it's fullest, as this really was worth the extra money. I don't know about you readers, but I disagree with using a OEM filter that is used on all of Mazda's cars, as opposed to a special oil filter for a special engine.
