Thanks for the additional info. The purification mainly centers around removing particulate matter in the >1 micron size range. There is no additive refreshment at this time. Perhaps 'wiped out' was a bad choice of words. Instead of the typical 'saw tooth' pattern where wear metals/contaminants...

Apologies of this is in the wrong forum, seems to fit here best, but feel free to move if I goofed. Curious if anyone has input about the outfits who pull oil out of your engine, 'super filter / purify' it, then put it back. Have the opportunity to save some cash in a HD Diesel fleet doing...

Are you referring to the original factory oil fill being synthetic? I’ve heard of that – though never driven a new car off a lot, so have not had any experience. When I last did research (7-8 years ago) there was a pretty good debate about break-in with synthetic vs conventional and the OEM...

Ah – I see some of your thought process now. Appreciate the additional info. Fuel dilution was a thought I had in the initial design stages too. Especially with the realization I’d need 1000cc injectors to keep the turbo properly fed on the top end. By boosting the compression I was hoping to...

Thanks REDDOG. Hopefully it will break in and be a long lived, high power engine. I'm pleased with the 30mpg so far - the original RSX was rated for about 27 combined on premium, so +3mpg, a lot more power, and E85 being 80-90 cents per gallon cheaper than premium works out pretty nice. Curious...

Thanks for the additional info. OceanDoctor - That's the E85 at work! My goal was to get some great mileage with a ton of power all while using dirt cheap American fuel. I've got a lot more info on the build thread link above. But briefly: 12.5:1 compression, ceramic coated pistons/chambers...

Bit of background... I've had my '02 RSX / Turbo on E85 for about 4 years. Clutch failure meant a great opportunity to rebuild the engine for even more power and compatibility with 105 octane E85. Did a bore/hone, dropped in some 12.5:1 pistons, eagle rods, a more efficient turbo, balanced &...

Greetings gents, Took a recent trip to Detroit Diesel facility to witness a teardown of an engine. This is a 60’s era roots-blown, 2 stroke, 2-71 DD. Our guys told DD that the engine was run on multigrade oil and DD guys flipped out and insisted that straight weight was the only way to go...

Lee, I took a look through the catalog and found a filter that holds about 40% more oil than stock, yet has the same threads and roughly the same diameter. Unfortunately the larger, higher flow, higher bypass pressure filter is not available in the higher filtration rating (Pure one = 98%...

I think the 30165 "premium plus" is rated at 4GPM while the 14459 "pure one" is rated at 3GPM. The pure one is supposed to be much more efficient, but it's also a much smaller filter and lower bypass pressure. As far as the engine, it's a 1.6L twin cam VTEC. The stock gearing puts it at about...

Finally got my "new" engine in the CRX and decided to get serious about the oil. Did some research on filters and found two filters that will fit my engine: Purolator Pure One L14459 - (Stock) Case = 3.15" x 3.03" 12-15 PSI bypass w/ anti drainback Purolator premium plus L30165 Case = 2.98" x...
