BAC5.2 Posted September 15, 2011 Share Posted September 15, 2011 I only put 2.5 quarts of oil in to offset the 60 weight oil I use. Twice the weight, half the volume. That's OK right?

boymk123 Posted September 15, 2011 Share Posted September 15, 2011 Do the subaru engines handle oil that differently? talking about engine design, s2k and subie are day&night different... and our dear Subie has a turbo which has a banjo bolt filter ...

galiff Posted September 15, 2011 Share Posted September 15, 2011 talking about engine design, s2k and subie are day&night different... and our dear Subie has a turbo which has a banjo bolt filter ... I'm driving the non-turbo version. There is a banjo bolt issue on early s2k's too. Not sure if it is the same issue, but they all had to be replaced. Not really sure what the banjo bolt even is. I had an AP2, so i never had the issue. Does a higher weight synthetic work fine? If i use Amsoil should i stick with 5w30? Link to comment Share on other sites More sharing options...

Max Capacity Posted September 15, 2011 Share Posted September 15, 2011 galiff, just use a good 5w-30 in your non-turbo 2.5 Learn to check the oil and top it off as needed between the 3500 mile oil changes. It doesn't matter if the oil is dino or man made. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

csbrown28 Posted September 15, 2011 Share Posted September 15, 2011 Hmmm....(get's up walks out and checks the oil.....) Guess I'm one of the lucky ones. Mobile 1, 2,500 miles no consumption at all. The oil is still clear but a few shades darker. Car just clocked 50k. Giving some thought to changing given what I'm hearing. And checking on a more consistent basis, though I think the guys that are doing it twice a week or less are being a anal... Link to comment Share on other sites More sharing options...
LegacyLove88 Posted September 16, 2011 Share Posted September 16, 2011 Wow, already? What weight dino oil was it using previously? What weight synthetic did you switch to and brand? Sorry to hear man Previously 5w30. Switched to 5w40 Pennzoil Platinum. Really regretting it. Edit: New oil pan and filter replacement 150 miles after switching to synthetic. Not sure if it's a coincidence or not. Either way subaru is asking about $700 to replace the pan and filter. So butthurt right now Link to comment Share on other sites More sharing options...

bmx045 Posted September 16, 2011 Share Posted September 16, 2011 5w-40 is encouraged for non stock or driven hard turbo subarus. Fact. Link to comment Share on other sites More sharing options...
LegacyLove88 Posted September 16, 2011 Share Posted September 16, 2011 Well it seems like they flushed the old oil and put in some new stuff. Probably dino 5w30. Hope they didn't just mix it in considering of what I previously had in there... Car seems to be running a bit more sluggish though. Definitely not as crisp as before. Think I should call them and ask em if they used dino 5w30 or just assume they did considering it's their standard haha. (You know what they say about assumptions..)

PearlBlueGT Posted September 17, 2011 Share Posted September 17, 2011 just a guess. Subaru folks seem to blame oil for their motors woes instead of the car maker & sometimes the person looking at them in the mirror. Mobil 1 is most popular synthetic so most likely in the most cars and when one has problems folks jump on the band wagon its the oil. The only real way to tell is a used oil analysis but seems extreme to me. so true!!! Link to comment Share on other sites More sharing options...
Rock_2.5GT Posted September 18, 2011 Share Posted September 18, 2011 there are oil analysis posts around the forum that shows 5w-30 mobil 1 wears much faster than other, store-bought brands and end up "thinner" quicker, potentially leaing your main and rod bearings at risk, also this can account for the unusually high consumption people experience with mobil 1 5w-30 As a contribution to this thread, I had a thunderbird that had over 200k miles... It ran like a champ with Castrol Synth blend or standard high-mileage. I replaced the trans in it and the rear main seal, and wanted to see how it'd run with Mobil 1 5w-30. After about 1-2 weeks it blew a head gasket. I'm not using Mobil 1 again, and I will not switch a dino oiled car over 150k to synth ever again. The Legacy has had Castrol Edge 5W-30 the whole time I've owned it (80k miles when purchased up til 120k miles today), and it does not burn any oil. Runs great.

Zardoz9 Posted September 18, 2011 Share Posted September 18, 2011 Have 2 '05 Turbo 5 speed manuals. Baja with 95,000 miles. Outback with 20,000 miles. Mobil 1 was constantly being topped off. Changed both vehicles to Motul over 70,000 cumulative miles ago. Oil level never fluctuates, (read burns) since. Just a thought. Tom Link to comment Share on other sites More sharing options...

DirtyDan Posted September 19, 2011 Share Posted September 19, 2011 The problems encountered by changing to synthetic with a high mileage engine is going to come from the superior cleaning characteristics of synthetics. The synthetics will clean gunk out of the motor at such a rate that an oil filter change after 500-1000 miles is a good idea. If you see new leaks with the synthetic, it's because gunk was clogging them up and it got cleaned out. A blown head gasket was either totally unrelated or carbonized oil was helping to seal the gasket and it was going to blow at some point anyway.

Have they stopped since switching? I'm kind of more sketchy about switching it up due to reported issues considering the cleaning properties when using synthetic. With that said, i don't think i'm going to risk getting any unwanted leaks given i'm financially recovering from this purchase along with the timing/water pump service Link to comment Share on other sites More sharing options...

LegacyLove88 Posted September 21, 2011 Share Posted September 21, 2011 Alright, I'm back. Leak is just about gone at this point! Awesome news, I know. And to think Subaru was trying to charge me $700 to repair it. I think what MAY have happened is what Dirty Dan mentioned. All I know is that it's leaking less and less. Almost nothing now Link to comment Share on other sites More sharing options...
DirtyDan Posted September 22, 2011 Share Posted September 22, 2011 Don't forget to change your oil filter and top it off. The sludge that gets cleaned ends up in the filter and you don't want it restricting the flow or by-passing. Just for something to chew on, there are several base oils used in synthetic oils. The most common is PAO (it's also the cheapest). The "high mileage" oils add a small amount of ester base oil. The reason is ester based oil was the original Mobil 1 base oil, and the one that leaked out of most motors in the 70's. What the ester does is soften and swell the gaskets, because it chemically attacks the rubber gaskets. A small amount in the oil blend can be a way to seal up old hard, worn gaskets and seals. It also has substantial cleaning affect, much more than PAO, and far superior lubricating properties. Ester is one of the most expensive synthetic base oils, but to run it unblended, the seals in the engine, must be compatible with it or it will cause major leaks. I tried it once in the mid-70's and back then I could change the oil (filter & 5 quarts of Castrol GTX) for about $5. Mobil 1 was $4.95 a quart. I lost a quart in less than 1000 miles and it was the same cost to change it out as to buy 1 quart and refill. What it did do was clean out my 30,000 mile motor such that it never held the same oil pressure afterwards as it did before. I didn't use a synthetic again until the mid 90's after I went to a Castrol school and found out why. Link to comment Share on other sites More sharing options...
LegacyLove88 Posted September 22, 2011 Share Posted September 22, 2011 Do you use synthetic now and would you recommend me going back to dino considering the lose of oil pressure? Link to comment Share on other sites More sharing options...
