I am planning to change my OEM oil to 10w60 oil.

I heard about this when I was visiting SVM.

Is there any car that runs on this type of oil?

please give your opinion on this.

The oil I mean planning to use is Shell Helix extreme 10w60 SM/CF

20L in a tub.

Ferrari 360Modena Challenge, and track oil for the standard 360 Moderna

Also for BMW M series cars.

The Shell Helix Ultra Racing 10W-60 meets:
API SM/CF

ACEA A3/B3/B4

Meets the requirements of BMW M

Ferrari Approved

VW 501.1, 505.00

MB 229.1

Fiat 9.55535 H3

Obviously a good oil. I'm not familiar with the Helix extreme. Not available in the U.S. The weight is right for high performance track driving, but I don't know enough about the additive package to make a good judgement. I don't trust most manufacturers to tell the WHOLE truth with their published specs. Mobil woule NEVER tell about their molybdenum disulfide in the 0W-40 without being pressed. Just look at the spec sheet. zinc and phosphrous, sure, but moly? Isn't that the girl who sat next to me in third grade. Yeah, right.

Anyway, make sure you really need that weight before you go changing.

In your opinion what is the best oil currently out there for a daily driver in extremely hot climates? (one oil, no mixing involved)

GT-R (no or just a few events per year): Mobil-1 0W-40
GT-R (tracked hard, with cool oil temps): Motul 300V 5W-40
GT-R (tracked hard, hot oil temps):Castrol TWS Motorsport 10W-60

I can give you a thousand reasons why. But, Nissan chose well for this engine for the OEM recommendation without very high temps from track. In the cauldron of track, things change some.

so even 0w40 for 650hp ? standard is ok but, mapped is going to worry me.

I do love those fast boosts from 30-130mph so that count as track?

Unless you get it hot, yep. Even mapped. Can you do better? Maybe. But it's a lot of mental wok for a small return. Trust me, I've done the work. The return so far, for the street, is relatively minimal.

Nope. Sustained high speeds with the foot to the floor for 20-30 minutes is what gets the oil really hot on a GT-R. You'll be fine with 0W-40, and may be best with it for your application.

Would you recommend then 0w40 for when I am driving on the street and then change to a 10w60 on track days
Or
Run 0w40 for both street and track and just change after the track event (I forgot what the temperature limit is for req change)

I mainly drive on the street so the second option seems to make more sense, but wanted to get your thoughts as well.

Thank you in advance

Depends on how much street and how much track, and how hot you're getting, and how low temp operation you have. If primarily street with the occassional trackday thrown in, then the 0W-40, but watch the temps. If you're getting close to the "change immediately temp" (check the manual - I'm not sure it's the same from year to year), then consider upgrading the viscosity some. (10W-60 if you're comfortable, don't do many cold starts with it). I'm working on a cocktail that's about 5W-48, with upgraded moly to match Nissan's thoughts on their custom oil that's used in the other Nissan VQ's (see below), and I think the ideal oil for our cars for a lot of track would be about a 0W-50, but the only one out there is Eneos, which is very hard to get, doesn't seem to be a group IV or V oil with a lot of ester, or have much moly. I've used it, but wanted a little "more" before I gave up finding the "perfect" set of results.

Your idea with running the 0W-40 and changing it after track days is very valid thinking. Everything else would be labor intensive. If I recall properly, NJ can get quite cold. This past weekend, at VIR, my early morning startup temp was 28degF. I'm glad I have a good low temp startup oil in there. While the 10W-60 is a great oil, its intended use is the BMW M series engines, and they are reported to be the "loose" type, where the 10W-60 will have better low temp pumpability than the "tight" nature of the VQ series engines. Nissan specs their special "Nissan Ester 5W-30" for almost all of the other engines of our type, but upgraded both the low temp startup spec, and the high temp spec for our engines. It speaks for how "special" our engines are, and what their special requirements will be.

It sounds like running the 0W-40 for the mostly street and changing after track may be your best approach, but if you're going to track A LOT, and getting hot A LOT, then other considerations could be made.

Shawn would you say I'm at risk with street driving and cold starting the 10w60 in my tropical climate where it never goes below 75F?

Just a little more wear at startup, but no real "risk". Engines wear. That's a fact of life. You can't separate bearings with a thin fluid and turn them off and then on and not have some wear. The 10 will wear a little more, but not excessively so. The tropical climate makes it much better. No biggie.

Shawn, what about the motul 300v 15/50 as a compromise, I am in Michigan and a frequent tracker but my track days are typically cooler (ie under 85 degrees) as such my oil temps even when tracking rarely go above 240 and I have a tranny cooler so for whatever reason that seems to keep the engine oil temps down also (tranny temps generally stay under 230). I would run the motul 5/40 in the spring and fall and 15/50 in June, July, Aug make sense? I still daily drive the car also (during the non snow months).

Shawn, thank you for your feedback.
I will double check the oil temp limits for 2009 gtr.
Wish I was able to pick up a Cobb secondary oil cooler.

That will do, but the 15 for startup, if you are cold at start (below 40) will be a lot higher than the 5. This will be partially mitigated by the large amount of moly, but it can only do so much.

My suggestion? Summer would be 1/2 5w-40 and 1/2 15w-50. Sounds like that would fit your temps best.

You'll be fine using just the 15w-50 if cold starts are few.

Shawn,

Have you looked at or considered Mobil One 0W-50 Racing oil? It can be ordered online through Mobil. It has more phos and zinc than 0W-40, and might be an issue for those have still have cats. I have been using it mixed with 0W-40 for South Florida weather ( I do not have any cats ), changing my mix based on the season ( winter 2 qts 0W-50 - 4 qts 0W-40 and switched around in summer ).

No. Four reasons:

1. I don't have spectrographic on this oil yet
2. Unpublished amount of zinc and phosphorous (I have two COBB catalytic converters, and the OEM downpipe converters - I wanna stay clean), and I wanna keep my converters
3. The kind of moly they are using in this oil is "confidential" - doesn't make me sleep well. It's a proprietary "organo-moly sulfur complex", and I can't get details
4. The cST at 40degC is 100 (while 0W-40 is 75), and at 100degC is 17.2. By comparison, 1/2 0w-40 and 1/2 TWS 10W-60 is 110, and 16.21. The Mobil 0W-50 is thicker than Mobil 1 10W-40 at 40degC. It's more like a 12W-55, and because it's a "racing formula" it meets NONE of the API or SAE qualifications. Given, the cold startup protection will be better than either Castrol 10W-60 or Mobil 1 15W-50 (but honestly, compared to the 15W-50 - NOT MUCH), but I have no clue what the rest of the chemical package will do if not changed EACH track event.

I got 10w60 in it now and testing. Just in case I got heater every night on in the garage to keep on oil on temp. 70F average in the garage. so far no problem.

Use 0w40 Mobil 1, and if you track often and see temps above the 'change immediately' threshold, change it after every track event.
