Oh WTH? http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=Oil_Supply Just read that in 2009 FP said to go with larger banjo bolt and oil line? Wish I had known about this change since I bought in the fall of 2007. Anway, checked IAM today and still at 1.0, so the ECU hasn't...

Aftermarket turbo hss been in place for 5 years/40K. Forced Performance 20G. Banjo bolt screens removed at the same time. Sourcing a log cable (got rid of APV1 when I went for a custom tune) to check IAM. I think the next step beyond checking for knock will be dropping pan, checking oil...

Along with the elevated Pb, did have visible flecks in the oil on the last two changes, which is why I sent the oil in for analysis. Is there a particle size between visible to the naked eye, what gets caught by the filter, and what can be measured via oil analysis?

Posted my first oil report here back in 2006, back again with the same car with more mods. Got my numbers back from Blackstone and just wanted confirmation as to what may be going on before I drop the car off for a rebuild. I sent two samples in, lead was high in one of the samples (10ppm) but...

Thinking about it when I decide on bigger turbo and supporting mods. A water/meth system that's properly tuned on turbo Subaru is usually good for and extra 20HP to the wheels. Injector is usually installed on the throttle body side intercooler endtank. There's a few different ways to control...

Yeah, I saw that... Going GC next anyway. Will get one done minus TBN just to see how the engine finally broke-in.

Did a dusty rallycross on the oil and had upped the power by 20% a month or so before the change, then my 'usual' driving. Figured it would be an okay test of the oil, and was just curious. Waiting longer on the PP I have in there now after long summer of driving into mountains, and will...

I've got two months/2100 miles on the PP 5W-30 in the car now. Why the **** am I so tempted to drain it and through in some GC that I got yesterday? Grrr... New turbo is down the road, for now, just tuned and some pipe replacement, good for 243/299 to the wheels. VF40 is the OEM turbo, a more...

Subaru rod bearings... Seen enough cases of spun ones to have me concerned down the road at higher power levels. In terms of metal in oil, anybody know type of metal used in Subaru turbo motor for rod bearings? Is a spun bearing more about oil film being too thin and letting metal-to-metal...

An oil analysis from last fall, never posted it. Pennzoil Platinum, lots of short trips, oil was changed after a mile drive to someplace flat. Gonna get the current PP checked when I take it out in a month or so, curious what high heat and mostly highway miles has done to it. Might give Castrol...

Odd that the PP 5W-30 is just a touch thicker than 10W-30 at @ 100°C, cSt... On the subject of volatility, the downside is thicker oil and a bit of loss correct? Had a few quarts of PP 5W-30 around and used it in a recent change that I'll be using over the summer.

Great site here, been reading voraciously the past week or two. Didn’t realize there could be such variation in viscosity with the same weight range of oil! Have 10W30 Pennzoil Platinum in my 2005 Legacy GT with Accessport Stage 2 mods (Uppipe and Downpipe) Will be setting off my first oil...
