By this do you mean that i cannot use it in my car? And that it will do damage?


You could use it without any issues, but GM won't recommend anything other than 0w30, 5w30, or 10w30 with 4718M Corvette approval.

So i can use it without any adverse affects?

One more thing to add, the car also comes standard with oil temp and pressure gauges, while the cars still cold, the pressure goes near to the max of 5kpa while under load, obviously i drive it very softly until its up to temp.

These leads me to believe that the weight of the oil currently in there is too thick, which is why i would like to stay at 5w, but then have the protection of a 40 viscosity.
 
Yeah, your choice of oil will be fine, but 5w30 may be better. If you see higher oil temps with the 5w40 I'd go back to the 5w30, but it's unlikely to be an issue in an LSX motor.
 
I just got offered some Royal Purple 10w40 today for a really good price, but then had a quick read up on it and saw comments stating that the Royal Purple thins out quickly for some reason.

Is any of this true?

Would you guys go with the ELF 5w40 or the RP 10w40?

Isn't that - 27,340 miles... ? First oil change?!


I'm pretty sure it was a used purchase. Oh yeah, and pics are a must for us Holden lovers around here!

As others have stated, GM specs a 5W-30 for pretty much EVERY LSx
powerplant, and the Vette's Mobil 1 factory fill is a fairly light weight/low viscosity 5W-30 at that.

Which Excellium 5W-40 is this (they seem to make MANY, MANY different variants of a given weight just like Motul, Silkolene, and Elf's parent company, Total)??
(I was trying to look up the cSt @ 100*C, and HTHS specs. )

In any case, I would NOT go to the 50 weight stuff unless you are doing endurance racing on a road course in constant 115*F ambients (and even then the 5W-40 should be more than enough for an LS2).

Most LSxes seem to 'like' oils in the low 11s to high 12s range for cSt @ 100*C, and HTHS numbers in the 3.2 to low 4 ranges.

YES, CATERHAM (and others) will likely (and quite rightfully) come on here and state that the ONLY way to know for sure is to use oil temp and pressure gauges, and monitor the engine under various operating conditions, but the above ranges are generally what stock, unopened, LSx clearances are 'happy' with.

here is the Elf oil i have purchased:
http://www.elfoil.com.au/products/produc...llium_SM_5W-40#

Its coming up to summer here in Aus, the hottest it really ever gets is around 40 degrees celsius, but an average summers day will be around the 30 degree celsius mark.

At the moment temperatures are peaking at around the 20 degree celsius mark and cools down as the day goes on, so we dont exactly experience super warm climates.

I just want to know if this oil will be safe to use...

I have also been considering taking it back and using some Royal Purple 10W-40, but would like to stick with the ELF as it has been recommended to me by my own tuner, and a couple of others...


Personally, I would stick with the Elf product. (I would even consider using/trying their stuff if it weren't sooo impossible to get in the States.

)

It is "safe", but that 14.1 cSt @100*C spec is a little high for an LS2 operating at moderate/temperate ambients, and NOT seeing any open tracking, etc.
It might cost you a tiny amount of rwhp, and an almost infinitesimal amount of fuel mileage.

I wish Elf gave the HTHS specs for this oil on their data sheets, as that is the more telling spec, as far as how the bearings "see" the viscosity of this oil.

Here's a photobucket link if anyone's interested:

NICE!!

Any plans to do; heads, cam, headers, intake, tune, etc.??


Just had headers, full 3" stainless exhaust, intake and tune recently done
smile.gif


Pulled 272.6rwkw, tuner said he was happy with that figure but the clutch pedal was sticking so he didnt want to push it anymore, said he might of been able to squeeze a bit more out of it.

Would love to do a cam but i think i need to stop spending on it at the moment, i absolutely love the sound of a cam, and would love more top end, but i cant see how people drive around on the street with a lumpy/loud cammed vehicle without getting hassled by the authorities.

I had constant troubles with cops in my previous vehicle and really dont want to go back to it, throwing a cam into my vehicle now with the headers and 3" dual exhaust the thing will just be too loud to keep the authorities away.

Well manufacturer recommendation is mobil 5w30, so i moving to a 40 weight i would think cant hurt it at all with 44,000kms on the clock now. It'll still have the quick flow at startup, but just that little extra protection at operating temp.

To be honest my tuner who specialises in LS motors recommended i use the 10w50, and said the 5w40 is too thin, however i dont feel comfortable using a 10w50 in a fairly young motor.

I think the 5w40 is a perfect compromise between manufacturer and my tuners recommendation...

So looks like i'll be sticking to the ELF, i was this close to purchasing some RP and returning the ELF, but i'll stay with what i know...

WOW, even in non-open tracked, and stock clearance LSxes?!?!

I guess the "thicker is better" mentality is STILL alive and well in Ozzieland!

^^^^That would have to cost you measurable rwhp/rwtq!!!

(I don't care HOW 'loose' the bottom end was built.

There's certain 'experts' who believe that at operating temp even a 10w60 will be super thin, so its just giving more protection that say a 5w30 at operating temp.

Again, I would agree with this on an open tracked, BUILT, large super high lift high rev range cammed, super high pressure valve-springed, LSx which is shifted at 6500-7500+ revs EVERY shift in an enduro type event, but for a STOCK internal street car??!
