thirsty for oil?

[Quirky]

Magnatec oil is fine.
Hell any oil is fine as long its the right grade.
Our budget motorkhana car just runs on $15 supercheap oil and that thing gets a thrasing still running after 2 years.

[CAMB01]

My old Levin with silvertop used about a litre of oil every 2 - 3000kms and that was after i rebuilt it.
Silvertops just use oil alot.

Magnatec is a horrible oil

Why's that?

Tried and tested?

Can't say I've had any issues with my bp-ze (Maz Infini), 4age (BZ Touring) or 3sgte (Caldina GTT). Certainly no expert on the subject though.

Tried a few differet oils (such as valvoline synthetic), but keep coming back to Magnatec.

Agreed. Toyota use Castrol oil in their workshops for a reason - the oil is good. Magnatec is just a little light for an older 4AGE and they start to drink it... But if you own a 4AGE that should be expected.


A racer I know used to run Castrol GTX 15/40 in his R32 race car and it stood up to the temperature well, but wouldn't last as long as Motul or other race oils... But then GTX is only $40 for 4L not $120 .

my old 4k drank about 4L or more of oil in 1000ks... also ate 3 spark plugs, so stop complaining

all tho it did turn out that one of the bores were cracked and it leaked oil out of every gasket it could

[sergei]

My 20v when ran on 10W40, would consume 1L in 5000km (it has already done 230k, hasn't got worse.). When I gave the car to my sister I switched to 15W40, now between oil changes there is no need to top up (although I do oil changes at 5k).

As for my GT4, I run it on 10W60 and it does not consume any of it for period between services (5k) I drive it hard, and it is approaching 166k.

I think people start having problems with oil consumption when they miss services for couple of times. The oil that is in the engine consumes its buffers and becomes chemically active, which hardens all the seals, turns into sludge and cools and lubricates a lot less. Oil control rings become worn (due to hard particles in oil), and/or coked, which leads to high oil consumption.

My old Sparkly car (silvertop) used about a litre of oil every 4 - 5000kms and that was after i rebuilt it.
Silvertops just use oil alot.

Sparkly car, Sparkly car, I like to drive me Sparkly car .........

dunno if thats the real reason in a lot of cases, its definitely not for their pricing anyway

im not a fan of magnatec either, but i have no real scientific reasoning for it, just lke most peoples like/dislike for certain oils. how can you really tell if an oil is good or not? i used to use protec in the race car and it wasnt suited for that, doesnt mean its a bad oil

[tim_blair]

i cant telll you exactly how much it drinks but it does seem to be alot

engine has done 195k

it doesnt leak oil other than the normal light coating over the lower half of the engine but no drips

ok so if im going to change my oil to something else what is the general consensis on grade and company

also how much should i put in? 3 liters? 4 liters?

To the full mark (but not over).
Use 15W40 grade.

I have always and still use Castrol GTX Modern Engine Oil 15w-40 in my race car.
Due to it being turbo tested and the 'better' castrol oils dont seem to absorb the heat out of the engine as well we found.

[4agtepwr]

I like valvoline, I tried vr1 which is a fully synthetic 10/40 race oil in my engine, little thin for the revs that a 4age can do and when i pulled it down after a year the mains had started to hammer a little, can really only put it down to the oil and the revs, now just use that in my mx bike, but xld 20/50 is awesome, seems happy as and i quite like it as its a really good quality mineral oil, doesn't use any and dosen't throw any out, I think bazz went to a 20/50 in his as well. I dont like magnatec. Only really for the reason that most of the engines that I have seen run bearings run magnatec, not very scinentific but good enough for me to never use it in anything I build

[Bling]

Chuck in about 3L, start it up and run till oil light goes off, turn it off and leave it to sit for a bit. Check dipstick and top up to suit. Low to high marks on the dipstick are ROUGHLY 0.5-1L. I say "roughly" and "about" as i've never measured it, just know when to stop pouring

[Lurkin]

yep.. any less than 15w and my ST drinks it... never measured how much but every time I would check it (roughly weekly) it would need a top up...

still does every now and again - but definitely not as frequently.

[tim_blair]

thanks heaps for your advice guys

next time i buy oil im gone buy 20w40ish

Magnatec is a horrible oil

Why's that?

I know people who have put that in they're car around puke and had it was literally baked to the engine. That was in a turbo application, I've also used it in my car and it turned to shit after 2000kms~. Oil pressure also was very low in comparison

Errrr not for me, and i'm pretty confident I give my car more death than you give yours...

Example: Ran Magnatec for 2000kms before the Manfield Trackday, most of which was on MR2 club runs in the area, driving relatively hard. Thrashed the nuts off it @ Manfield, drove home, oil is still a medium/light brown, still over the 'F' mark and it builds oil pressure up enough to kill the idiot light in about 1.5sec.

Bloody good i reckon

[KinLoud]

I've used magnatec in all of my cars for the last 9 years - this includes high km bluetop 4age in my racecar, then the 3sge, my high km 4age 20v Marino, 2.2l camry, dirty old high km falcon, 4agze trueno, and my 4afe corolla.

All of these cars got given a LOT of throttle and revs!
The 20v silvertop in the marino used about 1.5L per 5000km
All the other cars needed about 0.5L per 5000km

Why even reply when he doesn't seem to know anything?

There have been too many "It's using oil!" posts where you finally find out that they seem to think it should not need any oil between changes!

They do? Not in a well-working engine where all of the seals are fine..... You should be changing the oil regularly enough that it doesn't need a top up anyway, unless it's burning a huge amount, in which case something is wrong and should be fixed.

Well, at least I don't think so.

[Bling]

Snaps it's a VERY common thing in 20v's.

As for fixing it, a rebuild isn't exactly cheap compared to topping up the oil every so often.

[touge_ae101]

the thing is once you have thrashed a 20V regularly and kept it topped up etc, you appreciate how awesome these engines are that they just happily use a bit of oil and still take a thrashing. one of those 'you won't believe it till you try it' things.

only need to rebuild a 20V if it runs bearings pretty much. (or throws a rod )

20V's are just awesome.
