What weight oil do you use?

[Swifty1638]

Ok, I am a bit lost on this. As you all know, I got the talon running/tuned this year, and 4 days later the turbo blew (keep the PTE comments in a different thread, and this one clean). I rebuilt it, and now it's all back on the car, all good again..so far. My concern is that I was running too much oil pressure for it, and that caused it to blow. PTE is of NO help in trying to sort this all out, so I'm guessing now as to what caused it. Besides running more boost (36 vs 26-28 it was before) the ONLY real difference is the oil. I WAS running 10w30, but now I'm running 15w40. I am curious as the oil psi has gone up, idle it was 25, now it's 50. cruising/pulls it was around 75ish, now it's over 85-90 psi! Could this "flood" the turbo? Keep in mind, it's a thrust bearing, p-trim. Feed is straight off the oil filter housing, NO balance shafts. it's a -4 an straight into the turbo. I have a oil filter for it on the way, but I dunno if I should also be running a restrictior, or go to a thinner weight oil..opinions?

No lie Ive ran walmart supertech 20w 40 plenty of times. Ive done it alot but that supertech filter is pretty small, but with my saturn alternator a small filter is awesome

what do you guys think about that mobil 1 clean 5000 in a daily driver (jeep), and actually doing it at every 5000

Supertech oil and filters are both decent considering the cost. I'd run a supertech filter over a standard Fram anyday.

ANyhow, Swifty maybe consider putting an oil pressure gauge inline with your feedline so you can see the pressure that the turbo is seeing rather than the overall oil pressure. Just a thought.

I personally have never done anything special in regards to the pressure my turbo see's. I got my turbo from Bullseye, and I bought the feedline fitting (built in restrictor) that they recommended. That's about it. I've ran anything from 10W30 to 20W40 in my car, and I've never had an issue. I also never run an inline filter on my feedline. I remember the Sport Compact article from many years back where the guy from dsmporn.com was part of the Ultimate Challenge or whatever, and went through 2 turbos during the challenge, and turns out it was a clogged filter on his feedline causing the turbo to see not enough oil.

OK, I'm done rambling.

[Swifty1638]

yea, I hear you gotta clean that filter every oil change..But, I dunno what to do here..arg.

[Halon]

Get something other than PTE??? You can maybe just try a real Garrett, FP, Turbonetics, or also other non-Garrett based turbos maybe.

x2, Frams are junk. The local O'Rielly's in St. Cloud did their own little oil filter analysis and found that out of what they stocked, FRAM was by far the worst. The WIX actually had the most filtering surface of all of them. I am not sure what else they tested, but I know it was about 7-8 different brands or so.

[Swifty1638]

I'm PRETTY sure over winter I'll be doing a 4202 setup. Spools the same as this, but more power..that is..if I can sort this revving thing.

WIX makes the NAPA Gold line of filters. And NAPA gives a decent case discount too.

Anytime I get an oil filter I just make sure it has the anti-drain back valve and its not a fram. Then I'm good to go.

[Shane@DBPerformance]

-4 is too big of an oil feed line. Also, if you are feeding off the oil filter housing on a car without balance shafts, then you should run a restrictor or the FP Filter/Restrictor. It almost sounds like you are trying to blow your turbo seals with everything you are doing.

[sleepydsm]

I've got a FP red restrictor for journal bearings, and a -4 feed line, from the OFH. No balance shafts, unported relief valve hole. Seems to be working good for me.

[Swifty1638]

I ordered that red FP oil restrictor yesterday. Should be here thurs.

[GnArKiLl]

so if your running no balance shafts or oil squirters and have the oil feed off the ofh. you should have a restrictor in the line?

[s1ngletracker]

this has gone way off topic.

I've been using AMS oil full synthetic 10w-30 since i owned the galant. Car has been driving smoother since.

[4g63tcrazy]

Yea I guess I'll try rotella 15w40 next or maybe like a 10w40. I don't think I'll need that thick of oil.

[s1ngletracker]

i think i'm gonna try 20w-50 to boost my oil pressure more. Is this a terrible idea?

[4g63tcrazy]

What is your oil pressure at?

[Kracka]

20W-50 is a thick oil. What is your oil pressure currently at and how high do you want it?

Great Choice!
