EDIT: upon a thorough search. i see mixed opinions about magnatec. alot of people claiming its shit and alot of people saying its great. im just going off what ive been trained. so personal experience tells me that its a fine oil and copes with heat just fine.
I have used it and I have to say that Magnatec 10w-40 breaks down in 7000km of normal combined driving (at which the engine runs rough, I repeated this over 3 oil changes for 18 months), which is typical of a mineral oil. Even Mobil's Synth S (now Mobil 2000) lasts longer than that and keeps running smoothly.

Castrol calls that 5w-30 a fully synthetic oil and you have experienced it to be anything but by not being able to withstand the heat in the GTR. That is what I would expect to happen since it is only a "Group III synthetic" which is actually a hydrocracked mineral oil. It protects reasonably well like a synthetic when fresh but breaks down as quickly as a mineral oil under heat and pressure. That is why I always take Castrol's marketing with a pinch of salt, same for the reason why I don't consider Magnatec 10w-40 a semi-synthetic and the Edge 5w-30 a true synthetic because they just are not.

generally if your gonna use a minerial just do more regular oil changes at least every 5k.
Mineral oils generally break down more quickly with heat.
synthetic oils are more stable and don't break down as quickly with heat. They generally have better detergents & addatives.
I've used the magnatec & its fine so long as you change it every 5k, before it breaks down. More to use if its cheap, otherwise just stick with the FEO, its cheaper and will do the job just as well. I use to bulk buy this and stick it in my family's cars FEO is cheaper than toyota oil LOL, worked fine with all of them.
if your looking for value FEO & regular 5k changes.
If you want better protection, synthetic oil all the way.
I recommend 5w30 edge (good for daily driving & value especially when they are on sale)
Track - i use Motul v8100 - 10w40 (the ester based one)
Using the elf 5w40 at the moment. Haven't really tested it as i just changed to it.
I'm gonna give the Nulon 10w40 full synthetic a go next (not just cos of those fake Regoli tests). Looking from their tech sheets they seem pretty good and they seem quite value for money.
The worst oil i used has been penzoil, extremely bad cos it burnt like crazy.
I change all my engines every 5k regardless if i use minerial or synthetic.
If the oil burns within 5ks change to a different one, either its not suited to your motor or the oil is crap

based on my usages i've used;
penzoil (10w30 synthetic)
penrite (5)
vavoline (durablend)
FEO
castrol - magantec & edge (5w30)
motul - v3000 & v8100
mobile 1 - 10w30 & 5w50
nulon - 10w30
Shell - 10w30, Ultimate
Prob some others that i can't rem at the moment also
the only ones i had problems with were the penzoil & vavoline, which seem to burn for no reason.
on my b16 i've mainly used edge 5w30 seem to burn once i boosted the car, which is understandable, motul v3000 (which had been good very little burn). I've changed my oil as little as 2k at times or less. Currently using Elf 5w40

good point aaron. ur perspective backs up what ive just previously read. why they market both the oils as semi syn and syn beats me. luckily i use RP

Gimmicks to fool the ignorant consumer, that's why.
Just got to do our own homework and research.
-
but homework and research nets results that support both sides of the argument. ie. i read an oil review saying it is and another saying it isnt. i think an email to castrol will clear this up.

Their official stance on it now is that it is. There was a lawsuit in the US when the hydrocracked mineral oil first came out where Mobil sued Castrol. Castrol marketed it as a synthetic but was a actually a modified mineral basestock. But Mobil lost the case, so now every oil company can use call their human-modified mineral oil a synthetic. Which is kind of sad since it is similar to someone taking an apple, spray painting it and calling it an orange.
Having said all this, I have nothing against using these miss-marketed oils (except for Magnatec past 7000km). As long as we are not paying extra for an oil that is marketed as a synthetic but isn't. Also, that's one reason why Supercheapauto can afford to drop the price of their Castrol Edge 5w-30 "synthetic" down to $30-35 during sales and still make a profit. It is a cheap mineral-based oil. But at $30-35, it is good value and I buy those in bulk when on offer.

10w-40, fix the oil leak, use Honda OEM oil filter and the oil capacity should be about 4 litres. When you fill up, you should check the dipstick anyway.

Royal Purple is supposed to be a Group IV PAO synthetic that is blended with some Group V ester-based oil. Their claim is that they have the heat and pressure resistance of Group IV, but the protection and polarity of the Group V, making it stick to the metal. I've not used it personally, so I'm not sure on how smooth it keeps the engine running and how long it will last before becoming rough.
I guess from their description, you could call it a true synthetic version of Magnatec.
