Full synthetic on bottles today dosent mean 'full synthetic' needs to say 100% synthetic

motul chrono 300v is a grade 5 oil = aircraft or jet grade

motul 8100 excess is blended grade 5 and 4 = best value for money

something like castrol edge is grade 3 and u pay way to much for it.

I switched from 300v = bout 150bux to 8100x-cess which is 80bux; considering i do an oil change every 2000kms i make quite a saving lolz.

interesting.. i was thinking about running 8100 in my car when i run the car in low power mode, but low power is 340rwkw so maybe i should wait till i put a lower wg spring in.

Kinda sucks huh mate that companies can write 'full synthetic' and it dosent even need to be; just a blend.

The info on the grades are correct though:

grade 1 - mineral

grade 2 - blended 'fake' sythetic with mineral (castrol magnatec fits in here)

grade 3 - better quality synthetic ( castrol edge and mobil1)

grade 4 - higher quality

grade V - jet grade 100%ester ( 300v and redline oils fit in here)

Thats why i think 8100 is fantastic cos its blended highest grades which is still better than something like castrol edge.

its 5w40 as well; 10w40 is a bit too thick for an rb26 with stockish compression.

In terms of which viscosity of oil to use I think it will be a case of trial and error as this will depend on your bearing clearances, and will vary from engine to engine and will also depend on your oil pump flow and pressure.

My case in point.....I used Mobil 1 5/50 in my stock sr20. Oil pressure is fine and doesn't drop off at idle even after 30 laps around Barbagello. My brothers LS2 we tried the same Mobil 1 and it had shocking oil pressure at idle after giving it a hard time. Switch it to Castrol Edge 10/60 and oil pressure is perfect. Generally, there is not much variance in max oil pressure (probably due to the oil pressure relief valve) but it is at idle after giving the car a hard time when the viscosity is noticeable and oil pressure may become marginal.

Incidently, I just pulled down my SR with 40,000 klms which has done 100's of laps around Barbagello and the bearings were still like brand new using Mobil 1. I was going to try Motul 300v in my new build (after run in) but I am now considering staying with Mobil 1 given the excellent condition of the bearings given the flogging it has had.

Royal Purple is very good oil.. on par with the Motul. I run the RP10/40 in my forged engine no worries. As already said though, your engine builder should know what oil best suits your application.

Actually the Royal purple is a great oil but more on par with motul 8100. 300v is a clear step up in terms of ester content. Hence it is a lot more expensive.

i have just rebuilt my engine with acl 87mm pistons, tomei cams etc

what first oil should i put threw the motor? motul 10w40 synthetic? is this right?

Woah definitely not... Check with your engine builder but chances are he is going to tell you to run a mineral oil. Reason being is that he wants the rings to bed in. This won't happen very well with a fully synthetic oil and the engine will burn oil badly for the rest of its life.

A friend of mine who's spent a lot of his life as a mechanic working on bikes has tainted views on Motul oil , he does agree that the highest spec synthetic is good but wouldn't touch any of the rest of their range .

He mentioned that they market aggressively and sell on price . Read into that what you like .

His thoughts on synthetic oil pretty much start and end with Mobil 1 and in the case of hard worked bike engines he suggests Mobil 1 Racing 4T 15W50 . He mentioned that HRT uses it and at times they used to snag supplies of this oil going to bike shops who ordered it . You find it in 1 and 4 litre bottles which is a pain but some bike shops get it in 205L drums .

Whatever you use should be based on clearances and temperature range IMO .

A .

There are three oils i have used over the years that I wouuld not hesitate to use again. Motul chrono 300v. Redline, And Royal Purple. All have proven to offer good protection in extreme situations such as track, drag etc.

I have no particular favorite, rather more a case of what is available at the time.

They are all 100% synthetic and on teardown inspections have all performed admirably.

Some mechanics are total clueless asscracks if you ask me.

The head mechanic at landrover told me that the oil they use in my mothers discovery is castrol magnatech and costs 200dollars for 5 litres to which i replied "magnatec is only about 30dollars"

he replied "oh its renamed, its actually called castrol edge" (hmmm still only 70bux at autobarn)

Majority of mechanics know dick when it comes to......well 'anything'

Stealership!!!!!!!

lol

what i have noticed from the change engine is quieter ,oil temp down, oil presser down ,and after a dyno day today castrol made 304kw & R/P 309kw so i don't think that's to bad but i will try a 15/50 next.

15 cold weight is waaaaaay to thick for the turbo; in past i tried to run it and on coldstart you can hear a metal grinding in the turbo.

definitely no thicker than 10; actually make that 5w40-60

just a quick question?

for example 15w50

does it run 50w when cold and 15w when hot? or vice versa?

im running the 5w30 castrol edge stuff and my oil pressure is horrible and its only 1200kms old.

use to just run HPR10 and oil pressure was fine.

You mean dealership mechanics right?

its 5w40 as well; 10w40 is a bit too thick for an rb26 with stockish compression.

So the base stock of 300v is ester (or somwhat a variation of it)? From what I've read, ester is only used as an additive for blend with the base stock, so is the base stock of 300v is still PAOs (Polyalphaolefins)?

royal purple and motul 300v is around that price as well.

I think i'll stick with royal purple. Could someone confirm how long does 300v needs to be changed? I heard it dosen't last as long since its a race oil.

BTW, sticking to the topic title. I believe Royal Purple makes a run in oil (on the US website). Might be a bit hard to get it in Australia.

Compared to Castrol Edge 10-60 I found I got 6 months out of the 300v instead of 3 months with the Castrol. This was based on periodic oil anaylsis tests, the Motul retained its viscosity better in my engine. I also get no cold start noises from the Motul unlike the Castrol.

Johnny - I disagree 15w is too thick for a turbo, if you heard metal grinding on the turbo like you posted I'd say it';s a fair chance you had stuffed turbo bearings that would not be caused by the weight of the oil (cheap oil maybe?). I have run a 300V 15W-50 thru my pair of HKS 2530s for 5 years and they are both in perfect working order.

    • This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.
    • A full Veilside kitted JZA80 Supra in Meriken park in Kobe city a few weeks back
    • Its a well known brand in New Zealand; its a rebrand of the Rhino RAV3.  I don't know what the wiring difference *is* between the rev.1 (installed about 15 years ago) and rev.2; but as you say I would think its reasonable that it uses the same immobiliser relay circuits. I had a look but couldnt see a similar harness; but didnt move things around since I didnt want to mess with it   It was one of AVS well known Authorised Installers; I spoke to AVS themselves about it but theyre unsure hence seeking advice more so from the skyline community who are more familiar with the actual car and its wiring. Im in Auckland; but the installer is on the other side of the city so hes very reluctant to come back to even look at it to confirm something isnt connected into the wrong wire.  I dont want to drop the name since they *did* do a really good job for the most part. Everything is very tidy and he fully replaced all the alarm wiring, all the sensors, the wiring to the door motors, installed a switch which was never installed in the first place...really happy with the alarm install itself..just not this one issue. We all make mistakes, if it is the alarm, I just want my fuel pump getting proper switched, fused, power as it was; without having to shell out for an auto electrician to switch a wire and tell me it was the alarm. 
    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
