what brand oil do you guys use? weight?

[fiznat]

Just changed my oil a couple days ago, and I was just wondering what brands of motor oil you guys use, and also what weights (at what mileage). I went with a higher weight (10w 40) cause of my mileage (154k), but what about everyone else?

[krazy skwerel]

castrol gtx 10w-30. valvoline is really good as well. not felt the need to go synthetic though. :batman

[LaureltheQueen]

I would definitely NOT reccomend synthetic oil on any engine with more than 10-15k miles on it. Synthetic is mollecularly smaller than regular oil, which means that it stays together better at high temps, but it also means that it can fit in cracks where regular oil cant. That means leaks. Once leaks get started, they're damn hard to stop. Switching back to regular oil wont help either I'm afraid to tell you. When my mom got my 1991 subaru with 176k miles on the engine, and NO leaks whatsoever, from my dad, she immediately went to jiffy lube, and had them do all the fluids, and change the oil(synthetic) Now, approximately a year and 20k miles later, I leak about a teaspoon of oil every 24 hours, when the car's not running.

I use Mobile One 15w-50 in my WRX. Thing is a freaking heat box and needs extra protection. Only have 7,949 mi on her.

Pennzoil 10 W 30 in a brand new engine...probably will be changing my oil real soon

[Demonic240]

AMS Oil Synthetic 20/50W (wish they made a straight 30W) don't need multi-viscous oils here in FL.)

[98TURBOKA]

I use Castrol Synthetic 5w-50. I do have a small leak, but that's from the monkey's that I had put my turbo kit on and the crap weld job on the oil line. I've only got 46k on my motor though.

[UncleBen]

this is a thread for palmerwmd. i use mobil1 synthetic 5w-40 with 120k miles. car runs good with no oil useage or leaks.

[Evil98Silvia]

I use Mobil 1 synthetic oil, always have always will. My friend is trying to talk to me about MOTUL oil, but GEEZ why so expensive. For transmission I use redline, I use redline also for the rear differential.

[spec-u-later]

I use Mobil 1 5w30 synthetic. Im trying to find a place with Royal Purple.

[team23rulz]

Find a NAPA...they sell royal purple! And if you guys ever get a chance, buy Lucas Oil's Oil Treatment, that stuff is awesome, worth every penny! Real good for high mileage engines...

[team23rulz]

And if you REALLY need me to, Royal Purple is one of our race team sponsors, I could probably get you some, you would have to pay to get it shipped to your house though...

Dang ol dang, what is this supposed to mean?

Judging by the huge oil stain in my neighbor's parking space, I would be suprised if it had any oil in it

My accord is running with 10w-40 and probably will for the rest of it's life

[sultan]

i'm running valvoline synpower 20w-50 right now.my motorcycle is using Genuine(that's the brand) 10W-40. i know it's not motorcycle specific, but it was 60 cents a quart at wal-mart, and my bike is too damn old to care.

[GirlRacerS14]

Mobil 1 Synthetic 15w-50 for the turbo Runs great, no oil usage, no loss.

Very good Oil, and I am hoping your changing every 2k!!

That oil is also very good for NA applications, I am running that in my S14 with 95k miles, started using at 74k.

Laurel was right about being careful about using it, but I wouldn't say you can't, just depends on the application your using it on. How well the motor runs, condiiton of seals "oil pank, etc.".

Finzat, search up oil threads, Palmerwmd is the oilguru!!!!! and we have many good oil threads......

hope this helps...

Yep, my baby gets the best treatment. Oil changed regularly. Gotta take care of that engine.

[Former_240_s14]

That is good to hear, I talkd to someone the other day that is only running 10w-30, didn't know what brand, and is running 15psi w/out an intercooler.........talk about dumb...!!!!

I asked the poor boy if he ever heard of the word DETONATION!!!

I guess its true what they say........ignorance is bliss, lol :pface

[JDM]

I currently run Valvoline Durablend 5w-30 with a Fram SureGrip filter.

Rubin,Care to elaborate on why you need to change your oil at 2k while running Mobile One 15w-50?

[nismodave]

Mobil 1 10w30 now.

Switching to Royal Purple next oil change.

[GELLIS2586]

I use royal purple 10w30 that stuff is great 6,000 mile oil changes woohoo. its worth the extra money.

[Former_240_s14]

Rubin,Care to elaborate on why you need to change your oil at 2k while running Mobile One 15w-50?

Its not that it matters what oil you are running, its the fact that you are running a turbo application and your turbo has seals/etc that use oil. Your oil is getting used harder with a turbo set up and from my talking with shops and people that know oils well "aka Palmerwmd" they recomend you change your oil every 2k.

Your oil gets circulated throughout a turbo application more in comparrison to a NA app. Also, if you have dirty oil, or old oil, you are taking a chance ruining your turbo.

Does this make sense, its 2am and I am beat.

[Cold_Zero]

Rubin,It makes perfect sense. I was thinking of changing my oil ever 2,500mi. I have been monitoring my oil level and life each time I check my oil. I guess I will see how bad my oil get at 2k mi.Thanks for the info.
