Changed oil. Mobile 1 Synthetic to Amsoil Synthetic. RPMs feel a lot better.

 

Do you really feel a difference? Or is it the fact that the last oil you had was just old and so putting in new oil in general will make it feel better? I've been debating if I should stop using the oil that the dealership gives my car.

 

Yeah, boutique oils aren't really any better, new oil always feels nice, though M1 doesn't run so well in these, it's pretty thin.

 

I love Mobil 1. But i might try this.

 

Enjoy your boutique expense

If you want to try other good oils for the 350, Penzoil plat is nice, though i find Castrol Edge and Syntec (the new black bottle one) are slightly thicker in the same rating, and the 350 likes that.

 

Washed it and waxed it

 

Installed a motordyne space, changed the plugs, and sprayed the plenum while it was off.
Took her for a spin...she feels great, so smooooth.

 

To reply to Jah and all others, I only ran the Mobile Synthetic for 2000 miles. As soon as I put it in I noticed the RPMs felt real rough, especially high in the RPMs. I've read on here people were saying its not what it use to be and that they don't use certain phosphates anymore or something of the sort. Break-down of the oil is much more suspect when a lot of hard driving is done , etc. I had to get off the Mobile 1, it felt awful. Before I changed the oil I had drove it around, once I raised it up and popped the hood the engine covers, adjecent metals, etc where VERY hot. After I changed the oil and drove it around for 45 miles, popped the hood, everything was kool to the touch. RPMs felt much smoother. Idle sounded and felt smoother. Downshifting and deceleration feels great. It almost feels faster, as if the engine isn't working as hard or can run smoother. I'll never go back to Mobile 1.

To add a little more, I believe overall synthetic oils may feel a little rougher in these engines. As someone above me said our HR engines like thicker oils and the Mobile seems to be even thinner than others. The convetional oils may give engine revving much smoother but overall this Amsoil has been great. Everything is much improved over the Mobile. I've heard great things from Amsoil, even that its one of the best. I'll probably stick with it, even after my FI kit on.

Edit: F2CMadMaxx, I don't mind spending $10 extra on something that will better protect an investment. It is just a few dollars more and as they say, when you got the cheese- you can spend it. I am willing to shop around and may check out the Castrol oil as well. Especially if its thicker like you say.

 

I run amsoil everything on my car, and for all the 'boutique oil' = waste of money haters, honestly do some reading online and you will see why AMSOIL is king of oils.

My oil change interval is 12k regular driving and 8k hard driving, using amsoil 0w30,

Amsoil flows better then any oil on the market at low temps and high temps, while maintaining the ideal viscosity for proper engine operation and reduced temperatures/engine wear.

 

Don't get me wrong, boutique oils like AMSOIL are very good, but on UOA's they're not any better than a good regular oil like Castrol or Penzoil.

Also, erm, you might want to be wary of the massive marketing with oil like that, lots of 'planted' sites etc.
And, flows better than any other oil, yet maintains the ideal viscosity? It can only mean maintains it's original viscosity. Within say, a 5w30, there is lots of varying CST numbers, eg, a Mobil1 5w30 is thinner than a Castrol 5w30 (in the same class, synthetic etc)


As for Mobil1, yeah, i tried that in my old mustang, a very unfussy engine, got 1000 miles out of it, noisy engine, lifters etc, and really black, switched to *anything* else and all quiet and free running for the duration.

If you can find 5qts of AMSOIL for $40 let me know!

 

Thanks!

Thanks!! I think you mean't the guy before me? My handles are painted with the same paint as the rest of my car.

I will get the oem LED tails soon-ish. Possibly read leather interior from leatherseats.com to replace my hard oem leather.

Now I have to decide to install my Stillen Roof spoiler or not. It's already painted and ready to go, I just can't decide if I like it or not. It will fix the wiper nozzle.

Also, for the oil discussion, shell rotella t6 ftw.

 

i broke my TWM short shifter.. again..
its 2 pieces, and its basically a plunger w rubber stuffed into a metal cup that is the shifter base.. terrible design.
My pedal wasnt adjsuted right after my build, nor was my shifter plate.. so i was dragging it thru the syncros and haveing to rev match shift anyways..

so we said fk it.. and welded the hell out of it and polished it up..

the result was a properly aligned shifter, a properly adjsuted RJM pedal , and an absolutley soluid shift feel, zero vibration, play or slopiness.

Its like driving a ferrari right now.. i never thought a nissan box could be like this.

oh, and we were nerding out in the garage all day, so we polished everything even though wed never see the parts again.


got it to the shop using this lol:






the twm w the rubber cut off the shaft and inserted back in the socket:





end result.. mind you , this has an extra inch of threading down the shaft... and then we cut an inch off the top as well right at the tape line.. this lets my shifter arm sit farther down vs having a boot sitting way up.. ah the little details.





end result is gangbusters.

 

I know it doesn’t make sense but I installed DIY grounding wires on my 2004 Z roadster and I believe any low speed hesitation / flat spot in acceleration is gone, it seems almost like it shifts better and possibly has slightly more power. I guess it is like washing and waxing your car - they always run better afterwards. I was fully aware I might experience a placebo effect, but it seems real, so I am glad I spent the time and $40.

 

Nismo-how long are you going to go w that Amsoil sig series? Says 25k but curious how long others would go on this. I'm using XL (10kmiles) now.

I drove mine to Jacksonville FL (5.5hours) yesterday and about 1hr from home now in Columbia drinking a beer. I'm very proud of my little bugger. She did very well and I think she loves road trips.

 

Just recieved my final piece to my hopeful 700hp BP ST Turbo Build. Updates in May (when the build is final and tuned.)

 

Received me jdm cover yesterday afternoon and installed it.. Done for a little while with the engine bay.. before and after pictures included

 

Nice ratchet shifter, lol. I used a pair of vise grips when mine broke in half.

 

Looks great.

 

Wow. Looks nice.

 

Had my front bumper repainted along with my front mudflaps.

Having a new windshield installed today by Safelite.

Photos after I clean the car.
