Maybe we can make this a poll, or a sticky even. What oil weight are you running, what brand, and why? I've been using Mobil1 synthetic for a long time, now that I'm boosted I use Mobil1 5W30 (for winter), and looking for 10W40 for spring/summer/fall. Fully Synthetic btw.

Break-in oil when you first get the car or install your FI system? Either way, I used the same oil I normally do. I used Mobil1 5W30 and switch to 10W30 in the summer. Your tuner telling you 0W20 is very low to me.. You should be running at least 5W30, my tuner advised me 5W40 but I can't find it anywhere.

Side note: Eneos is friggin EXPENSIVE!

More like freshly built motor. Whats wrong with 0w20? Too much of a race oil and not a streetable oil or what?
I'm deff interested.

boosted technically run high mileage since they are pushing twice as much.. hence why high mileage is ideal for turbos although changing it every 2.5k-3k miles still required.

I thought turbo guys typically run extended performance. Anyone else chime on this?

0W20 is way to low. OEM recommended oil weight is 5W30, so going to a lower full temperature weight is not a good idea. We should be running at least 5W30, ideally 0W40 - 5W40 according to my tuner. I'll see if I can get him to chime in.

Just for everyones information, this is what oil weights mean:
Let's say you're running 5W30. The W stands for winter, the 5 is the weight of the oil when you're engine is absolutely cold. The 30 is the weight of the oil when your motor is at full operating temperature. The weights of the oil don't actually change, it's the viscosity that they correspond to. Meaning 5 is the viscosity your oil corresponds to at cold start-up, and it ranges to 30, which is the viscosity your oil corresponds to at full operating temperature. Hope this clears things up!

Good info about the oil. I actually didn't know that.

So my tuner is recommending me use the 0w20 but the internals are aftermarket....does that change my situation at all?

But the viscosity of the oil at full operating temp on the stock motor is 30, if anything yours should be the same or higher.

The viscosity is too low for turbo! If the manufacturer suggests 5w-30 on the stock engine then if anything I would move up to 5w-40 with boost

I have never heard of a boosted k20 motor running anything less than Xw30. Xw20 is too low, even for a supercharger. You should be at least running 5W30. Regardless of your setup, your oil viscosity rating should NOT be less than your motor when stock. Bad for your motor man.

Looks like I'll be making a tranny fluid thread as well, lol. Amsoil syncromesh is ok but not that good for our transmissions. You should use Redline MTL for OEM gears in our transmissions.

I'll also be switching to 0w40 for engine oil as per my tuner and a ton of other top notch guys (Geoff from FR) and see how it goes. I've been running 5w30 and 10w30, so hopefully the new stuff is awesome.

Another old thread I'm revamping, but I've been running Shell's Rotella T6 motor oil for a couple years after switching from Mobil 1. When I switched, I also went from 5w-30 to 5w-40. As mentioned before, the "5w" is for when your engine is "cold" (i.e. not up to operating temperature). The "40" is your oil's viscosity rating for when the engine is at operating temperature. Personally, I feel that when going from N/A to boost, the oil weight should always go up, on account of the increased temperatures (e.g. 5w-40, 0w-40, 5w-50, etc). Heres my reasoning for the weight of the oil I've chosen:

I live in San Diego, so our temps typically don't dip much below 60. So I'm able to run one weight all year. My weight of choice has been 5w-40 (as mentioned above). However, since I'm not running a restrictor on my JB turbo, my cold engine oil pressure is really high (roughly 70psi). So my thinking is that I'll start running 0w-40, since I need the 40 weight for operating temps, & the 0w weight to lower the pressure that will cause damage to the turbo's internals. This is purely theoretical, but it makes sense to me. :shrug:

I ran M1 when I was bolt ons, switched to amsoil signature synthetic 5w30 when I first went boost, but after hearing about the rotella I switched to that. IMO it is the ideal weight for a boost k series for the reasons above and because I need the 5w weight since I live in the mid-atlantic it does get below freezing here in the winter. I also switched from amsoil to rotella because the rotella can be found at typical auto stores/walmart for a reasonable price, and the amsoil is not sold at typical auto places and costs ~$10/quart.

Amsoil is really good, but to each their own. I personally can't afford to use that oil. Especially since I change my oil roughly every 3000 miles. An old friend swears by Royal Purple, but I feel its yet another overpriced oil brand. One brand I'll never use again, is Castrol. I had just installed a brand new turbo, & decided I'd test out their new Edge full synthetic oil as well. Big mistake. Roughly 500 miles down the road, & I progressively start puffing out blue smoke like a locomotive. It goes without saying what happened, & I consequently had to swap back to my old, worn turbo that I was planning on replacing the bearings in. Call it what you will, but I'll never touch anything Castrol ever again

The only way i can get amsoil is a shady house in the ghetto. The sign is all beat to shit and tagged, but if you knock 2 little asian kids will open the door. If you ask for Amsoil, they will say no words, run away and a petite asian little with come to the door and tell you to meet her by the garage. Once she opens it, there is boxes full to the ceiling of any kind of amsoil. must be thousands of dollars worth. Craziest oil pick up i have ever had.

I like the rotella because it was designed for turbo diesels so it has additives that will help with boost, it's affordable, and widely available. Also, bobistheoilguy has lots of good reviews/tests involving it, and they generally don't like mobil 1 over there.

Wouldn't you use the same weight for turbo superchare or na? You should also take in consideration your bearing clearances when choosing an oil weight. Turbos require little pressure for oiling, which why (ball bearing) use a restrictor. Even some journal bearings should use one depending on their oil pressure from the motor. I personally saw a precision 6266 journal, -4an feed with no restrictor completly fall apart from the bearings inside.

The rotella contains zinc additives, same with brad penn, which is great protection for motors. (bearings, cams, rockers etc)

I'm unsure of the whole weight of oil situation. Zinc additives are what I heard are good and ive put a zinc additive in the oil as a part of the oil change routine. I've mainly used 5w30. what oil weight should I use it I had for the rotella? I live in md it's a range on cold winters being sometimes 20's-50's ferinheight and 80-100F in summer.

I'm not an expert and would never claim to be. But in my opinion, 5w40 is a great weight for boosted k series motors, especially for us that live in areas that can get quite cold in the winter. The heavier 40 weight will help with the added stresses of boost, and ideally we want to maintain that 5w so the oil, when cold, gets through the engine as quickly as it needs to. Bobistheoilguy.com has a TON of info on all kinds of oils, if you really want to do some research that is a great place to do it. I like the rotella because it comes in the 5w40 weight, which is something that is not very common, it is readily available, affordable, has good additives, and the people on bobistheoilguy really like it :shrug:

Also, fwiw, Geoff of Full-Race recommends 10w40 for turbo k series as the 40 weight helps with the added stresses of the boost, but he also lives in AZ where it never really gets that cold so they can get away with a 10w.

For those who have cold, snowy winters, I would recommend running 0w-40. Reason is that when its cold outside & your engine is cold, you want your oil thinner, so it can get to your vital components quicker. The 40 is recommended because operating temp is going to remain relatively the same, so you'll still need that extra protection, even during the winter

whats up guys need a little help. Didn't want to make another thread on this being that my question has already been brought up. I have a fully built sleeved K24 with a Z1 head, I am about to strap on a GTX35r on it. The motor has about 1800 miles on it since the build. I've been using conventional oil for the break in. But now the question is what brand and what weight do you guys recommend for me to use now me being boosted? I have used brad penn 20w50 in my fully built 720hp evo, it was pretty good. Lots of evo guys use it and love it. Now I'm not sure if it was on here or k20a, I seen someone say that they use brad penn 20w50 on there boosted K and recommend it... what do you guys think? need a little help especially that my eg is almost done... thanks any input would be appreciated..
