My Oil choice.


Recommended Posts

Hi ppls,

Now the motor is well and truly run in I am going to go for the Motul 8100 X-CESS 5W-40. Its a decent synthetic oil that is PAO, i.e not a half arsed synthetic.

The next step up from PAO is the ester based oils which are big $$.

Close to $100 for around 5ltrs.

The Motul 8100 X-CESS 5W-40 is $59.95 for 5ltrs which is fairly decent.

It should be interesting how the 5w-40 goes, there is a bloke at Autobarn that runs it in his RB26DETT. Its fine and holds oil pressure in heavy traffic (unlike mobil 1).

Let me know of any experiences with this oil.

I'm not going to play around mixing oils.

$40 adds up over a 5,000km change interval.

I'll see how it goes, if the oil analysis comes back nice I'll stick with the oil and possible extend the drain intervals.

I've seen a few analysis reports with the Motul gear and it is a pretty damn good oil.

If the report contains a little too much bearing wear I'll jump up to the 300v.

I do quite a lot of kays ~30,000km's per year.

It all adds up. Especially Studying full time at Uni and trying to support my continual list of mods habbit. :)

Ive run Motul 8100 for the last 3 or more changes.

Found the response a little better than Mobil 1, but i have no idea about wear on bearings etc.

I'm thinking of changing to Castrol Formula R (a lot thicker tho) to see how it goes.

    • I do have a tiny tiny misfire occasionally but I think it's because I got a little fuel down into a plug tube so I'll pull the coils out and see if I can dry those out. 
    • Ok, so here the embarrassing 'fess up' post. Here's the crack, or broken part of the old valve cover. Pretty obvious break and in hindsight it's quite the face palmer 🤦‍♂️ but let me explain why I didn't think this was a problem. This side part of the valve cover is an additional piece, it protrudes from the main valve cover and it's also where the fuel rail mounts.....  You can see the rail at the bottom and you can see this external piece hanging off the side of the cover. It almost looks sandwiched in this pic.  Here's another cover with that side piece ...  On top of this, when looking at the inside of the cover, there were no openings(*) for that section. So I really just thought I'd broken some crispy plastic mount for the fuel rail.... Until somebody drew my attention to the air openings at the BOTTOM of the cover, not INSIDE the cover. So, I had a ginormous PCV leak. The cover needed to go and I should have taken everybodies advice and got a new one in the first place. The original one is just fried, its really brittle. It was nice to have the new one be really snug in position and the screws were slightly tight to do up which was completely different to the original ones that almost undid themselves.    
    • Pulled out this pile of shit, will be refreshed soon enough. Had coolant hit my face and I accidentally tasted it.  It's sweet.
    • Looks awesome. Well done. I'd love to drive Laguna Seca! 
    • This video is great, the enthusiasm is infectious and it's kind of cute. It's great to see these things being used properly on track, it reminds me of track days of old. It is a bit funny seeing everyone so excited about Skylines, whereas here they're all considered a bit nuggety or shitboxy. If this seems odd to you mr OP, imagine all of us being this giddy about seeing 30 C5 Vettes on a track at once place, full of influencers taking their videos and posting for clout. That said, you did a great job conveying the fun and excitement of a track day, getting out there and just having some damn fun.
