For what it's worth my father's E60 M5 runs 10-60; it redlines at 8300 or so and it's got the tightest tolerances of anything I've ever touched.

M5 is almost a race motor, with a huge oil pump to push that thick oil.

You are correct It's actually got four oil pumps and a wet sump though

I run Valvoline 20W-50 VR1 Racing Oil. Its great and thick enough for a high revving race motor. Never had a problem with it at all. You should try it. Its cheap and it works. I just wish they made a lighter oil in it. i would be happy with a 10W-50

I use Motul 5w-30 on my sr20det.It's good and light for my car in winter.When Spring starts,I use Motul 10w-30.I make sure that I use their engine cleaner once after 2 oil changes.It works for me.

where do you buy motul oil?

[akito]

ill be buying oil next week. if anyone wants in to try it out.
options available are
for the crazy enthusiasts on the track 0w-50... 8.50$/qt 51/box
then as follows for the daily drivers
0w-20 = 7.75$/qt... 46.50$/box
5w-20 $7.75/qt... 46.50$/box
5w-30 $6.25/qt... 37.50$/box

1 box = 6 qts

my old s13 ran on regular oil till i bought it withhhh.. 120k? switched straight to royal purple, ran for 20k... sold it.. current owner uses royal purple for another 15k, engines never been better.. still holds perfect compression. theres about 30k on top of my S14 SR on royal purple.. who knows if it ran with reg. or synth.. runs like a champ, perfect compression. i work at a car dealership.. when you come in for an oil change, the oil you get anywhere.. is absolutely the cheapest shit the owner will throw in there. all toyotas start with toyota motor oil for first 5k-15k miles, and then are switched to semi-synthetic that resembles slightly discolored water haha.. without a hickup. occasionally we get high, really high, or jesus.. its still running high.. mileage cars.. first time customers who decide to switch to synthetic on 400k mile sienna engines, and once again.. do it without a hiccup. maybe theres fact to whats being said, but 36 mechanics at my work, and of course at other places.. will tend to disagree that it will cause damage.. they just recommend against using synthetic if your engines leaking oil like a SS autochrome manifolds leak exhaust haha

People were not saying it cause's damage per se. What they were saying is the fact that a engine ran on petroluem based oil for a long time when switched over to synthetic would start leaking oil and be a waste of money and due to leakage could go down the road of damage if oil levels were not maintained because of leakage.
Now this happens to be a fact. Petroleum based oil over times swells rubber seals and gaskets. It also gunks them up with buildup. When you run a synthetic it tends to not do this and also does not gunk up. When that happens after using petroleum based oil and switching to synthetic it causes leaks because it cleans the gunk out and also no longer swells the seals. Thereby causing possible leakage and waste of money due to oil loss and if the owner of said vehicle is not careful low oil due to oil loss which can cause damage. These are all proven facts and many mechanics can attest to it.
Now if your engine is well maintained with a petroleum based oil not allowed to gunk up and does not have a lot of mileage than switching over is not a problem.
Though higher mileage engines run on Petroleum should stay on Petroleum for the above stated facts.
P.S. most higher mileage engines are not well maintained oil wise anyways and what I stated above rings completely true.

[sTalnOut]

i use GReddy GR2 oil

[boozels]

Torco is one of the best. Sr1 or if your baller the Sr5

What kind of cleaner do you guys recomend??

[steve shadows]

I use K&N , Mobil 1 or Nissan OEM for filters....

CLeaner? You mean engine solvents? for cleaninginternals?

I clean my engines via re-builds and hot tanking. thats about it.

[sideview_180sx]

im on my 3rd KA and my 2nd s13. all 3 engines got mobil 1 10w30. along with a standard tune up. and i've never had smoking. leaking. or a change in performance. these motors aren't built motors with tight tolerances. they are quite robust and can take a beating. don't baby it, beat it. and i also get amsoil at stupid cheap pricing. thanks to a sponsor. but i will be using that in a different motor. if you want clean oil. bite the the bit get a good oil filter. i have the trask setup and my friend is using the canton setup. super awesome filtration and i can run the oil in the car longer (currently 7K miles on the mobil 1 oil with the trask filter and the oil is still a nice brown). Good oil is only part of the equation, the filter is the main ingredient IMO. to having the best setup.

[illvialuver]

okay i just red this and im tired so i think i got confused. is it okay to swith to organic from sinthetic? i dont knwo what the person ran in it before i bought it.
and another thing, i hear that the est filter is the one from the dealership cause the filter isnt paper like fram. that just waht i hear and what i use.

[O3DigitalBath]

so how many people are runnin some of the thinnest shit they can find and a big oil cooler with theromostat so it doesn't thin out too much?>

[420sx]

well i ran alot of different oils... i really like 10w30 for how it feels. 5w30 a lil too thin, pressure drop. higher than 10w40 isnt necessary if u have a low mileage sr.
i use torco now. i love this stuff.

used redline. my favourite. this and torco.

used royal purple for 2 years. its ok dont get me wrong but lookin at the data its inferior to torco and redline
used all other offshelf stuff. ofcourse its not as great.


also look into amsoil. but if u gonna order anyway, then might as well use torco.

10w30 ftw. and i track my car just fine with it 1-2 (sometimes) a month. u could run an oilcooler and be golden.

[kandyflip445]

When I bought my car it was at 130k miles and had been on dino oil its entire life. There were receipts to prove it was changed every 3000 miles. The front main seal was leaking so I replaced that and switched to synthetic. Runs great, even better than before from the sound of things. I haven't had any leak trouble from the engine since the front main seal either.

I like Redline 10w30 in my car. I may try a 10w40 next but right now I'm running the AutoRx treatment to clean it out some. It has been getting more quiet since I started running the "clean" phase and I'm almost to the "rinse" phase. I'm using Valvoline for the AutoRx cause it says to use dino oil. Also, using a PureOne filter.

[Jung918]

I'm hearing a lot of good things about this Enios oil. I might have to pick some up from you.

[akito]

so now that hybrid performance posted up something before i did.... anyone interested lol
