Hi guy's, haven't had a good engine oil discussion in a while so was just wondering what engine oil you are currently using in your AU i6's & V8's atm, is your choice of engine oil performing to your standards & are you happy with it?
I'm using 5/30 Nulon full synth atm in my vct & its good but with summer here now i find its a bit thin around 35deg c where i'm located. Just purchased some Valvoline syn power 5/40 to try out & see how it goes. Hoping for the 5/40 viscosity to be more effective in the summer heat than the 5/30 fingers crossed, there are some guys here on AFF whose opinions i trust who have used the same weight oil in their vct's with great success, so i should be ok. So what engine oil are you using in your AU's at the moment & is it cutting the mustard this summer? Looking forward to all your replies guy's! ![]() ![]() cheer's, Maka

I wouldnt think the oil to be thin. Im sure when hot you will get atleast 25-30 psi. Connect a pressure gauge and you will know

I'm just using Shell HX7, courtesy of the Supercheap $20 sales.
I'm one the run the full 15000km intervals and never had a problem. Coming up to 400000kms now! Runs good in summer and winter. I haven't measured the temp of the motor with a fancy thermometer yet, but my guess would be the motor would be running close the same temp summer or winter. Or it thermostat isn't doing its job! |

I'm using Nulon synthetic 5w30 in my VCT Fairlane. Warm pressure seems OK according to the factory dash gauge. 95% of my driving is inner city traffic, and I run LPG, so the oil doesn't really darken (still pale yellow on the dipstick at 5000km oil change intervals).
My car was owned by oldies from the country most of its 250k life, so the motor's in decent condition and doesn't burn any oil in between changes, so I'll stick with the 5w30.

Hi 4vxc, i'm getting a bit of a tac noise on startup but only on stinking hot days, on cold days its fine, quiet as a mouse. Had a look at some oil temp charts & yep the upper end heat range of 5/30 didn't suit the climate where i live hence the one point increase in hot viscosity. Average summer temp on startup here is around 23c, winter is around 5c but on colder mornings can get into minus temps pretty easy!

Hi Sox, yeah i borrowed some good advice you gave on a previous old thread about engine oil choices. Considering you live kind've in the same climate as i do i thought your choice of viscosity was spot on for your climate & since it (your climate) is nearly the same as mine the choice of 5/40 will be pretty close to spot on for me too!

Fast flowing Nulon also means fast warm up times from cold, had a look at some oil temp charts & tbh for my location in summer nulon synth 30 weight is a little too thin for application imo. Will try the Valvoline with new filter & go from there. cheer's, Maka

Mineral oils get thicker with age e.g a 5w30 will head towards an SAE 30. Synthetic oils however dont thin and hold their viscosity. However the additive packages are depleted if the oil could be cleaned and additive pack restored you theoretically would never need to change the synthetic oil.
As for cold starts yes they will be effected by the warm weight of an oil because for example at 30 deg c a 5w-40 oil is thicker than the 5w-30 oil. You cant really compare the winter rating of the oil across different hot viscosity. E.g 0w40 vs 5w40 vs 10w40 vs 15w40 and then to compare 0w30 vs 5w30 vs 10w30 etc. As for your issue its not really an oil thickness more so oil draining away from places it needs to be. The 5w30 still offers better startup protection and ample hot protection for that engine especially when it is not seeing a race track where high oil temps become prevalent, on the road oil temp usually follows coolant temp. This is pasted from the S/C 5.0 Thread - Note the winter rating doesnt mean the oil is same viscosity when cold as its affecting by the viscosity at 100 deg C. Quote:

No worries oils and their multigrade ratings can be a bit difficult to understand however once you get your head around it, its good

I also have a FG that had a slight tick on startup, just did the 15,000km service using HPR5 again no noise. For what its worth my AU11 Fairlane has 79,000km's and has been using HPR10 and is nice and quite also. |

5L Fairlane
i am using 10w30 according to what my glove box book recommends. Must be a oil for diesel as well for example : SN/CF not SN alone or CF alone Double check your book too for this I am using 10w30 Royal purple HPS atm the moment no issues I have used Penrite 10w50 and 5w40 full syn in the past no issues. Always use a new Z9 and sump plug washer

SN/CF is more or less the generation or oil. We have moved all the way up from SH SL SM etc etc. I think The SAE set requirements that the next generation of oil needs to be and deem if an oil meets that specification. AFAIK the rating takes a lot of characteristics of the oil e.g its ability to resist thickening with age.
I think the current spec is SN. Heres something I found notice how the SN beats the older SM spec everywhere. Quote:

Thanks for that 99AUXR, you explained the ratings beautifully mate!!!

i was running penrite hpr10 10w50 in my 220 kw xr8, the engine loves it, reasonably quiet on start up and holds oil pressure in the heat..
ive now upgraded to penrite hpr15 15w60, only because ive gone forced induction and it gets pushed harder than before, again still quiet on start up and holds good oil pressure when hot... |

Do you have cold idle and warm idle oil pressure readings?
Just wondering as when its cold most the oil is probably going through the bypass circuit. That oil has 175 cSt @ 40 deg C and 23.9 cSt at 100 deg C. Just wondering why you have gone so thick. To thick and you will have issues for the above reason. When you accelerate instead of pushing oil through the galleries it will by pass causing oil starvation. Oil pressure readings will give you a good idea, whereas noise isnt really ![]()
