I use the Castrol Synthetic R 5w-30, will be switching to the Castrol EDGE 5w-30. Its the best oil i can get off the shelf in Broome, and i got my last bottle of synthetic R for $65. I recommend the Synthetic R, and the EDGE is supposed to be better.

Its a daily driver, just cruising no thrashing, done about 130,000 kms. Engine is in fine running order, going to be interesting when i open it up for a rebuild in another 15,000kms.

cheers

I've ran castrol 5w30 in the past, I found the motor used a little of it over the 5k period.

The usual motul 8100 5w40 it doesn't use a drop. I've also ran castrol 10w60 (oil pressure was simply too high) and Mobil 1 5w50 they too didn't use a drop.

I've found that Mobil and Castrol tend to go "used" prematurely - you start burning oil after 3000km because it's worn out.

Motul 8100 is brilliant stuff and always lasted me 5000km without using oil. Also, 10w60 is too thick for street use IMO.

It all depends on your driving and how many kays the cars done.

We stress too much about oil...

Grab what ever good oil you want it won't make or brake it.

I've never had issues with either mobil 1 or castrol not lasting 5000km's, I have however had issues with oil being used when its a 5W30 oil, 5w40 is fine and the lowest I would go.

personally i think the 10W60 is too thick. far better to choose a good synthetic ester 10W40. and yes i have used the castrol 10W60. personally i think motul chrono 300V 10W40 is excellent stuff, but I will know more after the next analysis.

Beer Baron,

Have you done an analysis on the castrol 10w60? I'm keen to see whats in it, being if castrol skimp on moly and what not. ;)

I did one on it (castrol formula R 10W60) about 3 years ago, but i'm not the sharpest tool with oils and ingredients etc. Just wanted to see how the engine was really. from memory my mechanic that read the results said it was ok, but nothing out of the ordinary. and i still think it's too thick. there is no need for a 60. maybe if you do track work and a too tight for an oil cooler running the really thick stuff may be a bandaid, but providing you keep oil temps in check with an oil cooler i think 10W40 is fine.

I'll post up the results on the chrono 300V. my instinct tells me the results will be good :laugh:

Castrol doesn't use Moly from what I've seen. No big deal though, Moly is overrated. 300V has the highest moly concentration I've seen.

Kinks, how do you know the oil is 'worn out'? Just by looking at the color, it doesn't tell you anything.

Natrually Cubes you wouldnt have used a drop of the Castrl 10W60 or the M1 5W50 because they are thick as :kiss:

    • Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!
    • Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.
    • Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.
    • Yeah, saw the ratios, not impressed. Would like the punch I have in the first gears now. With those ratios it won't be the same.  Also want the h pattern gearing, or at least a quiet gear set that don't need to come apart for service each year. Looks like the only "reasonable" way Is a 8hp70 transmission, but where is the fun in that🤷‍♂️
