Motul is the good oil!

[95GTST]

I know everyone has their different opionion but I'd just like to say that I'm sticking to the Motul 6300 oil (I think that's it). I regularly change my oil every 3 months. On my last oil change, I decided to go with Mobil1, the car didn't seem to like it too much and after fitting my FMIC I couldn't see any changes with fuel economy (which I thought you would).

So anyway, the time came to change oil over the weekend and I was disgusted to see what my oil looked like!!! It was jet black, bubbly and well, you get the picture.

After putting in the new oil, I just got 480km out of a tank! Previously the car was just pushing 400km...

I have to agree that Motul is pretty good stuff. I had been running Castrol 5W-30, but swapped over to the thicker Motul 8100 5W-40 which is designed for turbo cars. I had no problems with Castrol beforehand, but I wanted something a bit thicker for the summer. It was the same price as the Castrol 5W-30 (but less than the 0W-40 and 10W-60), and I have found it's pretty much the same or better. Oil pressure has increased slightly but noticably, and my economy hasn't suffered at all. Since my economy remains the same I may as well keep running the thicker oil all year round.

I'll be sticking to Motul in future. I think because it's not as widely known about as Mobil, Shell, Castrol, etc, it tends to cost less for the same or more quality.

Motul 4100 or 8100 is the only Oil I use in my car. My baby purrs so I don't see any need to change (although I don't have any fancy gauges etc to keep tabs on anything).

Costs me $40 at the local Autobahn, speaking of which i'll be clocking up my 5,000km tomorrow so looks like im doing an oil change this weekend. :headspin:

wat's the Motul recommended specs for NA RB25DE ?

If you want the best, use Motul 300V if you have deep pockets

But yeah, Motul is definitely up there with the best.

Btw, jet black oil doesnt mean its shagged, especially with a full synthetic like Mobil 1. Usually just contaminated from blowby and internal engine cleaning.

I have only used motul 4100 turbolight (10w40) and I find it great. Its a semi synthetic, and it still comes out with a bit of a gold tinge after a tough 5000-7000ks.

Everybody I know that has used the Motul 300V Chrono has given it a big thumbs up, I will use it when I have done some more mods and running a bit more power (and my pockets are deeper).

Genisis32 - 4100 turbolight will go alright in a RB25DE - a mate at work is running it in his 33 gts (NA)....

unwritten law - thks mate. will give it a try soon. been using mobil 1 since forever.

How much is Motul 8100 5W-40 for 5L and where can i get some around west Syd?

I got mine from Autobarn in Chatswood and cost $55. I think all Autobarns carry it, but best to ring them first as mine was the last bottle on the shelf.

The guy tried to talk me out of buying it, he said it was too thin :confused: I asked him what he would recommend then, he said at least 5W-50 for street driving and 10W-60 for the track. I told him factory spec was 7.5W-30, and he said that was fine on a new, unmodified engine then started going on how I'd spin bearings etc even with a 40 weight oil and light mods.

I bought it anyway because I trust what I've researched on the web and what guys in here have had to say about their oil, and so far my bearings are fine. In theory they should have shit themselves while I was running the Castrol 5W-30 for the 10000km before this.
