The Goods On Oils

[niZmO_Man]

Most of the post is what they feel/hear/see/smell and nothing factual .

How about this?

I changed the oil on my GT-R on the weekend. Out came 5L of 10,000km old Penrite Racing 10, in went 5.5L of Premium 5. It shut the head up on cold start (few seconds of valve train noise).

Redline 15w50 or Lucas 20w50? Which one u will choose? Cruising temperature between 74 to 84 degree. Heavy traffic will be 84 to 98 degree

has anybody heard of the new oil type that motul are putting out now dany at garage 101 mentioned it to me one of there reps came around talking up a new race oil that is supposed to be super high quality unsure on the weights ??? motul swear by it and has backup from some of the fastest race cars around that are using it . apparantly bit pricey compared to your normal 8100 motul or whatever it is i havent used motul in a while i cant remember what the names are

does anybody have any insight into this ?

Ummm. mogul 300v

[Hadouken]

Dang motul

[omnigear]

did you have the valve train noise on the previous oilchange?

Nope.

It was a tongue in cheek post. The noise came after some thrashing. Oil was getting old anyway. The point is, any decent oil will protect your engine, provided you replace them (and the filter) regularly. Since most of the time my GT-R is putting around in economy mode, I change the oil every 10,000km (hence using $75 oil).

So I have being using GW Synx-3000 semi-syn oil for my car every 5000km or 6 month for a while & I'm wondering if I go with a full-syn oil would I be able to extend that interval to 10,000-15,000km or every 1 year?

Reason being I'm too lazy & the Car (basic bolt on mods) is currently used by my mum driving back & forward to work, which is only ~6km or so & probably never sees boost (besides the time I take it for a drive).

short distance driving is normally considered "Harsh" driving by most manufactures, which in turn calls for more frequent servicing. I would stick with the 6 month, 5,000km. I would not extend it to 10-15k, but thats just me. Im fussy.

Bought some Penrite 10W-40 Everyday plus as it was on special & $1 (almost 6 Yuan worth of savings! ) than GW Syn-X 3000.

Will see how it goes but my initial verdict is: probably would make f**k all difference...

I have noticed that the Penrite Premium 5 (5W-60) runs hotter (operating temp seems to be 90-100°C) than Racing 10 (10W-40, sits around 85-95°C-ish).

It might be the design of the oil, but I definitely need to run an oil cooler.

I use the same oil as ANGRY Anderson , he was in a bat mobile in the VFL Grand final

ULX110 for me

I noticed the same thing going from Liqui Moly 10w40 to 10w60, I think the extra pressure causes the oil to heat quicker... or something.

I will be going back to a 10w40 next change as 100psi oil pressure cruising at 2500 revs seems excessive. lol.

[MrStabby]

Its normal to expect thicker oils to make the engine run hotter. IIRC its because of less internal friction and higher thermal conductivity of thinner oils, but don't quote me on that.

I asked the question in another thread and it was answered regarding Nulon street and track 15W 50 vs Nulon extreme 10W 60. I usually use the 15W 50. I have a track day coming up and bought more of the street and track. What I don't understand is the difference between the two. In this instance I am obviously wanting to know which would be best for a 25DET, standard internals with bolt ons maing 230ish rwkw. I would like to know about it so I can make my own decision. I have read through here a bit but people tend to use abbreviations and I have no idea what they mean.

15W-50 will be fine. Just monitor your oil temperatures and if you're creeping around 120C maybe look into getting an oil cooler.

[FordyR31]

I don't have an oil temp guage. An oil cooler will be on the list at some point. Thanks.

Liam, once your water temps starts to climb, back off.

[Jazzadub]

If you're basing water temperature on the stock gauge, by the time it starts to rise, it's already too hot!

At least I have heard this is true on R32-34 gauges.

[niZmO_Man]

They're normalised (on the R32) so yes, if it's rising it's overheating.

On the R31 they're not normalised. Still, if it's gone past 3/4, cool it down.
