Best Oil To Use

i disagree with that statement Rezlo, as there are two viscosities, regarding the temperatures. The lower the viscosity rating during cold is better & higher the viscosity during running temperature the better.
So Mobile1 has 0w, which means it;s the thinnnest during cold start up, remember the oil doesn't get any thinner then this. While it's going into running temperature, then the 40w takes care of the higher temp.

if you read the manual, it doesn't recommend 30w as this doesn't cater for the higgher temp. or if you're using it it says you can't run the car hard for long periods.

This is what the manual says, I'm sure softec is brilliant, but this is what I have read in the nissan manual.

Also, because we run in a hotter environment, then the second viscosity rating should be taken, so anything with 40w & higher is better suitable.

One thing is for sure - I am learning man. I sit here in front of computer with Mobil 1 container in one hand. Was slighly worried about the 0w-40, but then WooHaa's explanation put me at ease again. I notice the abbreviations and list at the bottom of rezlo''s post. I see Mobil 1 states all the same and more like VW, Porche,Opel,Merc's etc.

While you are correct in the temprature ranges, you must also realise that 0W is design for -40 start up,

if you compare a 5W-30 without a turbo rating and one with a turbo rating you will see a huge difference. See in a mormal motor it will give you 30 when hot, but in a turbo motor which is hotter it will drop.

a 30 turbo aproved oil will run closer to 40 if not 45 when used in a cooler NA motor.

Another thing to remember is that all the old nissan service manuals do not cater for todays hi-tech oils available.

the Softec being a 5w-30 is approved for near all mass produced turbo engines specific for South African climates.

Another thing ALOT of people dont realise is that ball bearing turbo's can not use thick oil, they have to run on ligther weight oils with the turbo rating or you stuff its bearings up, especialy he ceramic ones.

And as it says in the S13/S14 FSM on page 20, 5w-30 or 10w-30 i prerable regardless of driving conditions.

like you said, freddie, I'm not getting into an argument, I'm learning as well. & there is an awesome exchange if idea's and knowledge, which makes this forum brilliant.
I called Castrol one day as I couldn't understand the difference between there Castrol RS 10w-60 & edge 10w-60.
the reason I also called was because edge is R200 & sumthing & RS is R400 & sumthing

The technician explained the difference to me, but there is so much more than just meeting apci standards. This guy explained some stuff I too still don't understand. He basically told me, it's not just the running temp, but also what loads, do to the oil & how long they can withstand it before they loose viscosity & what happens to oil, that is hot, then cools & then get's hot again.

Easiest thing he told me that we all will understand, is you get what you paid for. 🙄

I follow. But now feel quite comfortable to look at rezlo's product too. Better choices to make, and yes there must be thruth in prize for quality.

Nuren, I notice the Mobil 1 is only 4 liters? Not used to that. Good quality, less qauntity and more bucks 😂 😂 😂 😂 😂 😂

That's right...
Hopefully more quaility 😮

I suppose we all have our own opinions and are learning, I can say, previosly using oil when I felt the dipstic with oil on I could feel the oil feeling very thin and not as "slippery", I the tried edge sport an it felt better, when I feel the dipstic it still feels thickish and very "slippery", that tells me that it holds it clamed viscosity well, as for the noisy lifters in the morning, it's still there, but I won't buy mobil 1 just to make that quiet, it is moore importent to me that on high temp and work load the oil does it's job.

ok I'm confused. I've just come from volvo, picked my dads car up from service which is a 2.0 litre turbo.
so I asked the guys here and they use castrol magnatec 10w40 through their whole range of cars.
this is what I'm using.

Castrol catalog says softec for near the full range of volvo's.

Magnatec is not suitable for turbo charged vehicles.

Yes... Uhm... But... What if.... No

Maybe he and I had a communication gap :idea: 😕

Hey guys, anyone found any pricing on Softec yet or a place that regularly stockis it?

From autozone I get Edge 10w60 @ R185 for 5l
Mobil 1 0w40 I can get for R310 for 4l but they hardly ever have reliably

My car is still running the Valvoline that Snail put in after my bearing job, not sure what it was, but I will be changing soon as its done about 3500 kms

I get mine from midas, Its right around the same price as edge.

Which reminds me, my K&N filters finnaly arrived for the RB's 🙂 time for an oil change. yay

One word ............FUTRON for RB engines...mine still gives me no shit after oh two years...

Castrol TXT Softec LL01 R49.95/L @ Midas. They were only available in 1 L bottles. I bought 4L, but havent used it as yet. Had to use up remainder of my old oil (Sport Edge) I was using first. Next oil change will get this treat.

smart man 8)

Yip also found it at midas... but only in 1Ltr bottles 😕 I actually want to contact Castrol help line and ask them why I cant get 5ltr bottles anywhere

it only comes in 1L i think, that pic i posted is a 1L bottle, ive never seen it in 5L's anywhere.

Ok... Wonder why? Isn't that oil some sort of fill'm'up additive? of some sort...

Weird that one doesn't get 5L or 4L bottles...

Dont know why they dont sell it in 4 or 5L Bottles, even the Vw and Audi dealers keep them in 1L's on their shelves.

It definatly isnt an additive. its just only sold in 1L bottles
