Vq25Det Oil Thread - So The Major Repairs Thread Isnt Derailed

[scotty nm35]

Synx 3000 is definitely not a crappy oil. And I did mention stock M35... I would still run it in mine without hesitation. Whacky logic? Ok... Sure... There are plenty of Stagea's running around on it without issue.

We are driving low priced cars now, I was offered a working Stagea for 6k the other day... If you feel the need to blow $170 on an oil change, go right ahead.

Synx 3000 is a only semi-syn, and AFAICT GW don't publish HTHS specs either. Running a semi in a turbo car is not worth it IMO.

By whacky logic, i mean that you're suggesting a shorter OCI (which is more conservative) but a lower grade of oil (which is less conservative). To me that combo is mixed up.

No need to blow $170 when the Valvoline and Shell are in the $60-65 range, and you can get 6 quarts of American M1 on ebay (so no Australia tax) for $70.

What's wrong with a semi, better than running around with a raging boner...

US spec M1, isn't that a 0w? Go for it I say, see if you logic holds... I will stick to what works.

Very interesting read on oil if you have the time to read the article...

Can't read; Emo forum wants me to be their friend.

I thought Emo's were happy alone?

[scotty nm35]

I would copy and paste it but it is many pages long. Worth the read anyway...

[whitestag]

just wondering if anyone knows wheres the best place to get neo from. can only find the one place that sells it.. getting annoying.

[MrStabby]

How much does the Neo cost? Unless its cheap I would just get the same weight in something else full synth. Its good, but there's plenty of good oils around.

[Jetwreck]

Neo's about 120 for 5 lts.....but its good for 8-15k on a standard setup.

Ouch. On most motors if you're paying that much you'd be better off with Redline or Motul 300V which IMO are better oils at about the same price. Maybe the neo additive pack works particularly well with the vq25det?

[whitestag]

its just whats in it at the moment, 2nd change since new turbo,thought i stick with it as i do give it alot on a regular basis. i dont like 5k intervals. i like 8-10k

huh? Tried redline.....the 32 burn's it......while Motul is good it still doesn't match up to the Neo. The last time we used Motul it came out of our engine pretty black.....the Motul always comes out clean.

[scotty nm35]

The Neo comes out clean I assume?

Clean means the detergents aren't working well, which probably means it is more of a race engine oil.

this is correct

How did you make the assessment that it was burnt? Or do you mean you had to top up?

In what way did the Motul not match up to the Neo?

[Jetwreck]

Figured out it didn't stand up as well the same way we do it at the end if every race meeting. Dumped it and sent it for sampling.

I've used Liqui-Moly LEICHTLAUF SPECIAL LL 5W-30 for about the last 15000km at 5000km change intervals. My car's very close to stock with 70000km. Never had any problems with this oil, as far as noise or consumption goes, and happy with performance. It's long-life approved for BMW, MB, VW etc, but I just use it cause we only use Liqui-Moly at work and it's the one their website recommends for our engine. I get the LL for free but if I wanted to pay and probably after car gets nearer to 100k I think ill put the LEICHTLAUF HIGH TECH 5W-40 in.

I'd recommend Liqui-Moly oils to anyone but I wouldn't try change your mind at all if you've found a brand you like and trust.

one enthusiast in Russia made a great job

it's not close to you, because our oils are too different, even when they have same names

but it's GREAT. use google translate and look at pics. take a pleasure at looking

i found this one some months ago, and happy that run the Aimol 5-40 oil since 2008 on my third Stagea now. 240000 km on it on current car.

5w40 would be a good choice for you, as in winter is gets a lot colder than it ever would here in Australia.

Analysis of Valvoline Syn Power 5W-40 below. OCI was 5500kms. I found out from the manual that the factory OCI is 5000kms not 10000kms.

Interesting points are;

- High silicon - my guess is that this is due to the horrible old air filter that was in the car when i bought it. Will check again to see if this has come back to normal next change

- The oil has sheared down to a 30 weight. Not a particular problem in itself since there is no abnormal wear, and Nissan speced down to a 0W-20 for the motor. However, all the info i see here and on BITOG is that VQ motors are tough on oil. The loss of viscosity supports that, however, I dont know how shear stable SynPower is. FYI the published viscosity for SynPower is 13.9, after 5500kms its at 11.9.

- TBN is still really high at 9.1, most are happy to run down to about 1 before condemning the oil. This is an indicator of additive level. Additives get used up in use.
