Hi Guys,

Just wondering which oil is better for my R32GTR. Motul 300v Chrono 10w40 or the 4100 turbolight. My cars only mods are exhaust and coilover suspension and will stay this way for a while and running stock boost. Any info would be appreciated. Thanks.

300V is great oil but probably overkill on a street car (others would beg to differ :dry:)

4100 is only a semi-synthetic, which means it's about 15% synthetic and 85% dino juice.

I would go for the Motul 8100 5W-40 myself, either that or the 300V and do an oil analysis at 5000km to find out what it's like. You would probably find the 300V will last for extended oil change intervals if you're not being hard on it (track work).

For what it's worth, I've read that the 4100 is better for the older motors. It was something about the detergents in the full synthetics cleaning too much of the gunk accumulated in the bores and suffering blow-by as a result.

:D

Considering you have a stock motor, you might aswell go between the two products. The 8100 would do a good job. 300V is overkill and the 4100 is nothing out of the ordinary.

cowie165, thats an old wives tale. Its like saying you should warm your car up for 10 minutes each morning.

i've been using the motul 4100 10w40 for a while, no complaints here. Though i'm thinking of moving to a higher weight 10w50 or something, so might give mobil1 a shot.

hard to compare 4100 to 300v chrono, because the 300v is more than double the price or something...

I found this link ...Although it dosent relate totaly to motul its very interesting the differences between the ratings ...

Maybe we all should be running Diesel Synthets :)

    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
