Genuine Nissan 7.5w30 engine oil

[Greg]

is the genuine nissan 7.5w30 engine oil any good? i just changed my oil for this stuff on the weekend...but i have no idea how to tell if its doing the engine good! It's only $29.95 for 5L so if this stuff is alright then I'm going to be using it from now on

cheers

Its what nissan say u should use.

[wrxhoon]

its just plain old mineral oil that some oil company makes for nissan , u can buy same stuff for $20 . i only use fully synthetic oil .

[Guest RedLineGTR]

its what is in the user manual. But thier are much better brand out thier. U can get "GTR" oil nismo branded but made by Motul for like 80 bucks a litre if your keen on nismo stuff.

[Zahos]

Can you confirm Greg that it is in fact a mineral based oil? Does it say so the bottle?

[_turtle_]

did u get ur oil filter from nissan too? if so how much is it there?

[JezR31]

its probably stuff like castrol GTX2 with a nissan sticker on the bottle

[RBN1]

The oil is $25, the nissan filter is only $8. Amusingly its the same one as whats used in my Datsun Sunny

Nissan also say your car only outputs 185-206kw too. And they say the drain interval is 10000km

I wouldn't use it unless my car were stock. As it is, I pay more for some better stuff and change it twice as often.

Sorry to steal your thread, but whilst we are talking oil. I got some Penzoil full synthetic,now my oil temprature runs a little higher then it used to on a blend .Is this normal.?

[JezR31]

the synthetic oil probably takes the heat from the engine better than the other stuff you had.

Gavin woods put the nissan oil in mine,

its seems to run fine

havent used any other oil yet though

for the RB25DE the recommended drain interval is 15,000 km :bs!: i change it every 5,000 km, of course. on the bottle is says to change oil in turbo engines every 5000km. the only mods i have done are full exhaust system and pod filter so internally there would be no more stress on the engine than a stock one (i think?!). anyway thanks for all the replies

[Guest RedLineGTR]

In a general opinion i would change it at 10,000km for a n/a and 5000km for a turbo u can never change your oill to much thoe. The fresher with less particles the better. So whatevers in your budget.

i think i might buy my filters from nissan now. thanks for the info. for 25bux mite even try out the nissan oil lol.

the mechanic who did my major service put in penzoil synth 15-40 in my car. my suggestion is not to use that oil as at mid rpms, say 3500+ on the highway, the pressure is real low. it seem that at that amount of constant revs (hume hwy) the oil either broke down/foamed badly or was to thick to drain down through the motor at speed the pump was putting it back at the top.

i'm about to head up the gold coast & i'll be changing back to helix 0-40 as the oil pressure was much more constant and stayed higher on the gauge

I recently changed the oil in my r33 GTST to Penzoil Synthetic 15 - 30.

I don't know what sort of oil was in there before but the 15 30w hangs around the 2 mark on the pressure guage at idle and rarely above 4 on freeway driving. The previous oil would idle round 4 and be around the 5 - 6 mark at 3000rpm. Some people have told me its bad to have low oil pressure but can't tell my why other than the obvious NO OIL!!

[rs73]

Have you thought that a thinner oil may cause the oil pressure sensor to read a bit low or maybe fooled to think the pressure is lower than it is....?

[Greg]

cyphen, the oil pressures you mention sound about right. oil pressure of 2-3 once warmed up is perfectly healthy and normal. when warm mine idles at about 1

Greg, what oil do you use? On mine idle is a little bit less than 2, and between 2-4 when cruising, and up to 4-5 when accelerating. Maybe can even reach 6 on very hard launch.
