After 100,000 miles, my '95 SW2 burned a quart of oil every 600 miles (every 2 tanks of gas approximately). Oil burners, indeed! (love my Subaru now, next to no top off oil... 0.4 quarts once on 7500 mile OCI)

Ray H, If you use a denser than air gas like carbon dioxide, you don't have to monkey with positive pressures at all, just fill the airspace with CO2 and seal it (of course, I'm assuming the bottles are upright when you seal them ) TallPaul, Your suggestion to squeeze all the air out of the...

Is the airspace in quart bottles of oil filled with inert gas to prevent oxidation before it get put in your engine? I'm doubtful for quart bottles, you can crack the top and let air in/out, but for the 5 quarts jugs that I've bought, they had foil sealed tops. I'm asking because a PP rebate...

WOT could be abusive in the following scenario... You buy a used car, previously driven by Grammy Jones who never took it above 1500 rpm (and that was by mistake!) for tens of thousands of miles. The top piston ring can create a wear ridge at the top of the travel of that piston ring. Fast...

OK, I did some googling, and it appears that it isn't a nation-wide thing, but for those states that have banned MTBE as an emission-reducing gasoline additive (and those who haven't yet, like MA where I live), 10 percent ethanol is rapidly becoming a defacto standard gasoline blend. This...

Now that gasoline has at least 10% ethanol in the USA, will everyone now have clean fuel lines, intakes and valves? I've read many places that ethanol is a terrific solvent for gasoline related deposits, so I'm asking... will this be the death knell for fuel additives? I've also read that...

Replace your radiator cap... I had my system pressure tested 2x by the dealership, and both times, no leaks were detected... so it dawned on me, where do they pressurize the system? Through the radiator cap connection! Replaced my radiator cap, and the slight coolant leak I was detecting when...

I personally saw a bigger mpg increase while using Lucas UCL compared to FP60, which I use religiously now. Too bad I didn't take better data, but I remember it was about 5% increase in mpg vs about 2% with FP60... I would love to get better mpg... maybe when my 2 gallons of FP60 run out, I'll...

I had a 95 SW2... and at 112K miles, it was burning a quart of oil every 600 miles. It was ugly. Unfortunately, this was before I knew about AutoRX. I definitely would have tried the AutoRX before trading it in, but before that, I was replacing oil so frequently, I went out to 6K mile OCIs. I...

YMMV = your mileage may vary (just another way to say past performance is no guarantee of future results)

They are both made by SOPUS (Shell Oil Products...), so it begs the question... is the latest incarnation of Quaker State synthetic made of the same base stock as Pennzoil Platinum? Johnny?! There seems to be a growing body of evidence than PP is the real deal, and may become the GC-type...

Shell 87 octane gives me about 5% better fuel efficiency (mpg) than any other brand (no-name, Mobil, others). And considering the high price of fuel now, given the 9 cent difference between Shell and no-name 87 octane is about 0.09/2.30 (about 3.9%), it is totally worth it penny-wise to run...

Good for you... my Subaru 2.5 (2002 Impreza TS, SOHC) took a definite mpg hit running GC versus M1 0W-30. I wish it were as simple as "All N brand engines get better mileage with X brand and weight of oil"... real life is much messier.

Triple_Se7en, I added 0.5 quarts of M1 0W40 during this interval. And no, the crankcase was not overfilled at the end... it's been written here before that the carrier for LC20 evaporates, leaving the active ingredients behind, thus you don't end up with an overfilled crankcase. dkryan, you are...
