Was doing some reading here over the weekend and am going to try the oil mixing route on my upcoming change. The posts I read all say mix T6 and Rotella T, which I cannot find here. Is Rotella T4 the same thing with a different name? Sorry if this has already been asked. I did search first... but I'm old and stupid.

Thanks

First thing I would look for is if it's JASO-MA and/or JASO-MA2 certified. According to the spec sheet for Rotella T4 15w40, it isn't.

OEM SPECIFICATIONS AND APPROVALS
SAE 15W-40 API and OEM Approvals
API CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4, Cummins CES 20086,
DDC DFS 93K222, VDS-4.5, MACK EO-S - 4.5, Caterpillar
ECF-2/ECF-3, Ford WSS-M2C171-F1
Link to the spec sheet:

Hmm, odd. It said it on the back of the bottle I looked at yesterday which is why I wanted to post the question first to make sure.

Shell Rotella T4 Triple Protection SAE 15W-40 API CK-4

Edit... Ahh, your link took me to T5, Was asking about T4. I see the phrase "Enhanced wear protection" on the T4 sheet. Somewhere in this oil section I seem to remember that phrase being a no-no. I confess though, I'm not sure. I read hundreds of posts and all the info is still jostling for position in my nugget.

Well, there ya have it. Either I missed it, or the specs have changed. Either way, if it has the certification, give it a try if you like.

Another good link with lots of info. It's important to know the JASO ratings are from Japan. The MA and MA2 are for use with a wet clutch. I'm not seeing anything in the other ratings for wet clutch use but that doesn't mean they aren't; just that it isn't addressed.

So is there a consensus? Is T and T4 the same and is that what everyone is using to mix with T6 these days? Thanks

QUESTION.....Why mix? Why not use T-6 by itself? Many here do that, including this guy.

I did that for a long time.

A very good oil is Lucas full synth or semi-synth. Both are JASO MA2 rated. One of our high mileage riders has been running the Lucas full synth 20w50 for a long time now. I'll let him chime in if he wants to.

I think if I lived in a cold weather location I would lean toward the 10w40 and if I lived in the south where it gets over 100 degrees daily then the 20w50 would likely be the better choice but both will work in either location. For daily short distance rides; I'd use the lighter weight oil.

Well honestly, I never thought about doing it until I was reading all the posts about it on here. I've been using amsoil forever and it seems like (I have no proof and have never done an oil test) it wears out fast, or whatever word you would use to describe it. The motor gets noisy, shifting gets noticeably clunky or loud. 3 to 4k. I change and it quiets down and shifts better. Now I always have changed oil anyway at 5k so really I don't plan on gaining anything in that dept but since an oil change was due I thought I would read up and see about a change. I never even thought about using T6 (I've been using it for years in my diesel trucks) until I read up on it here. If T6 5w-40 is good and wont cause me an issue in the FL heat then I'm good with it. Thanks man.

Before going to T-6, my engine's lifters would clatter for a while. Since T-6, no more. That's cuz it starts at 5W, so it circulates faster. Being a Diesel engine oil, it has a heavier additive package to protect the innards. And since I'm a frugal type, T-6 is half the price (or less) that MC specific oils. I sent a sample in after inadvertently putting 7K+ miles on it and the report came back saying its in fine condition and there's another 2500 miles left on it. That's good enough for me to want to stay with it.
Re clunky shifting--preload the shifter, shifts will be smoother and quieter.

I used Amsoil for a good 25K and the price started getting to high. Switch to T6 last year and really haven't noticed any difference. Seem to shift about the same and 5K between changes and never uses a drop. Never understood mixing oils. To me it doesn't many any cents

T6

As per your suggestion I to have switched this winter to T6 and I must say...I have ridden 4 times now in 30 degree weather or there abouts....the sun was shining so was close enough to a nice day for an excuse to ride LOL....there was virtually no noisey clicking on start up and ran smooth and quiet....so far very happy with the switch!!!

Ride safe,

Rob

The vic oil doesn't even have a single certification.


Well, ****. I’m glad I don’t use it then.

I have a jug of the T6 out in the garage so I looked and yep; it is JASO-MA2 rated but when I look on their website it doesn't show up. Very odd. One would think they would yell it from the rooftops.

I mix T (T4) and T6 because I did the homework and had multiple samples tested and the mix tested best. Looks good and sounds good doesn't mean squat.

I keep a jug for mixing, when it's empty I fill it half way with T6 and the other half with T4. Couldn't be easier and I know it's a 50/50 mix unlike other semi-synthetic mixes you buy off the shelf where you don't know the ratio.

Your posts/information was the reason I initially considered it. I'll still give it a go I just wanted to make sure T and T4 were the same thing before I did. Thanks man.
