RLI BioSyn 0w-30, 13796 mi, 1997 Integra Type-R

[d00df00d]

Yes, that's almost 14k miles -- on a 100 hp/L high-RPM engine with a 4-quart sump, and engine oil that definitely was NOT designed for long drains.

Previous thread with details on the car: https://bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Main=141601

The previous UOA was on the old version of the formula. This UOA is on the updated version, which has much more antimony and much more shear-stable VIIs. On top of that, the chemistry has settled in a bit, which further improved things.

On the flip side, fuel dilution and nitration increased, the car saw more hard use (i.e. WOT all the way up to 8600 RPM), and obviously the OCI was significantly longer.

Results: Oil consumption has dropped (now 1 qt/2600+ miles and still falling), shear has vanished, all wear indicators are the same or better, and -- this is what gets me -- it looks like we could have squeezed a few more miles out of this run without too much worry.

It's almost unreal. This relatively lightly additized oil is producing stellar reports and running incredible OCIs in this engine. We are getting the benefits of an "energy conserving" oil without the drawbacks -- not to mention incredible cold-start performance without poor high-temp performance or shear stability. Needless to say, we are sticking with it for the next OCI.

If we could just fix the tune, I bet we could squeeze 20k out of this combo...

Less than 1 ppm iron per thousand miles is really good. All the other values are pretty stellar too. I'm not sure I'd run it much longer, however. The TBN is getting fairly low.

Link doesnt work. Looks like that NOACK is lower even than the 5w-40. What was the basis for your selection of the 0w30 vs the 5w40 that everyone talks about? Just the acura spec of 5w30 for the engine?

Im thinking of running the 5w30, 0w30 or 5w-40 in my 135i since it is a DI engine with the same specific power as the integra, and such high typical oil temperatures...

 

[BrianEM]

And all of that on a Mobil1 oil filter!

and 'scuse me, my engine makes 111.11111111111111hp/L, mister!

I wouldn't say the car saw more hard use than the previous sample, especially considering this OCI didn't see any Tail of the Dragon driving

One thing I am doing more and more is engine braking and rev-matched downshifts when approaching lights and traffic. I enjoy getting 28-30mpg daily (even with some fun driving)!

I'm excited to run this oil again in my car, hoping consumption will continue to drop. I'm thinking I'll run my next OCI out to 14k again, considering I don't feel like dropping the money on a tune right now.

HERE is the correct link!

 

[BrianEM]

Oh, and as of the time of this sample, the oil was run for just under 9 months, from October 13th 2010 until July 1st 2011.

Pay no attention to the datasheets. They are afterthoughts. The fact that so many of their HTHS values are ">2.9" is another example.

We were hoping this application wouldn't need the additional anti-wear properties or contamination resistance of the 5w-40. I guess we were right.

The 0w30 offers significantly better cold flow and lower friction than the 5w-40, not only because of its viscosity but also because of how it is formulated.

Lower oil consumption and even longer OCI capability probably would have been further benefits of the 5w-40; my brother feels, and I tend to agree, that those would not be worth losing the 0w-30's benefits -- especially since the situation might improve even further with the next OCI.

I would suggest doing what I did: try the 0w30 first for a relatively short OCI, see how it holds up, and go from there.

And a tiny one, at that.

I stand corrected.

 

[d00df00d]

Another thing to point out: the air filter was 30k-40k miles old at the time of the previous OCI, and evidently is still holding dirt just fine. Score one for Amsoil's EaAU line.

Does your M3 spec a 30wt oil, or a 40wt? Will you be going to the 0w30 in the M3?

 

[addyguy]

With a TBN of 1.3, I could see going 15k, but probably not 20k.

Also, I'd say you are at the end of this run, b/c the oil has thickened up somewhat to 12cst - virgin is around 11. NOT that this is a big jump, but it is showing that thickening is just starting.

Impressive run.

 

[buster]

Very impressive results.

It originally specced an xw-40, and common wisdom says it "prefers" thicker oils. BMW back-specced it to LL-01, and wants you to use its ubiquitous 5w-40.

I definitely would go back to the RLI 0w30 if I could. Maybe I will if the fuel dilution goes away and my engine stops stressing its oil this much. For now, I think I need the RLI 5w-40 HD.

If the tune improves, TBN probably won't deplete as quickly. The next run might improve things as well as the chemistry settles in further. We would only attempt 20k if all of that panned out.

I think so, too. The vis @ 40º is slightly thicker than the virgin spec as well.

The oil will be changed shortly.

Poor Type R

I wouldn't run oil that long in such an amazing machine but that's just me.

Evidently the Type R is doing just fine. I think what you mean is that you're uncomfortable.

Interesting. I think you mean ubiquitous 5w30? Dont think BMWNA sells 5w-40 LL-01... Maybe Im wrong.

I think 5w-40 would be for my 135i then. Cant imagine fuel dilution or oil stress in my N55 is that much less than yours... thoughts?

 

[ltslimjim]

I too believe a balance should be struck; TBN aside, with knowing to change the oil before thickening to the point of deposit/insoluble formation.

Yes, I did mean 5w30. Sleep deprivation is a strange thing.

You likely do have fuel dilution to deal with. What you don't have is an aging engine with (likely) worn piston rings. On the other hand, you have a turbo.

I do suspect you could benefit from the 5w-40 HD. However, unless you're going for long drains on top of everything else, I still think the 0w30 should be a starting place. If it falls short, it probably won't be catastrophic; if it can take the abuse, it's just a better lubricant.

In other words, I think of the 5w-40 HD as a product you use when you have to, and the 0w30 as a product you use when you can.

 

[garlicbreadman]

im using 5w30 in my integra and there is hardly any consumption. maybe 1/4 quart over 5k miles. but i dont have a vtec motor..maybe a vtec swap if this motor mysteriously blows

He thinks the results would be better if you changed out the oil every thousand miles. RLI is some interesting oil to say the least.
