Suitable Oils

[boon]

My V7 had Motul 5w30 (I think?) in it for a while, ran bloody well when it was fresh, I want to say noticeably better.

Cost an arm and a leg though. Back to edge 5w30 for me.

Chapter 3 of Motor Oil 101 starts to talk about synthetics. This site will also help you choose a viscosity, and explain how and why your oil wears. If you want to continue talking about oil until the cows come home, they even have forums dedicated to talking about oil.

Oh joy, there are people who have less of a life than I do, I could think of better wet, slippery & sticky things to talk about... Paint for instance!

i have a customer that drives a late model bmw, he swears by doing 30,000kms intervals, everytime we service it we have to pull his cartridge oil filter out in little pieces with long nose pliers cause it disintegrates.

but hey he thinks he knows best lol.

This is not normal, I've mainly only seen aftermarket filters do this. The genuine ones do 70K before this happens.

Not saying I agree with the long service intervals, I think they are to long for NZ conditions but I change oil on BMW's all day everyday and have only ever struck 1 Genuine filter that has come apart. Jap imported E46 328i with 73000Km on the clock. Never had an oil change.

this is interesting i think im gonna do an oil change... from wat everyones saying im gonna go 5w-40.. my math says 5w= good for the start up with forged pistons and rings and 40= it can get its ass threw the little hole that leads to the gt3082R once oils hot..

Hey guys, am about to do an oil change on my v4 sti. It's done 160 000k's and is completely standard. Previous owner told me he's been using Penrite 10w60. i normally use castrol magnatec 10w40 or motul 10w40 in most of my previous cars with similar k's. What would you recommend? Stick with the 10w60 or change to something like Castrol magnatec 10w40? Cheers

[G-unit]

just found this thread, have gone and brought some valvelen engine armour 10w-30, got royal in there for now, mechanic said there oil will last 15,000ks, crazy, will change it before then tho,

Definately the Magnatec over the Penrite! 60w is way too much.

[Navin]

Yeah thought so. Just picked up some fully synthetic 10w40 Motul oil today

[Guest]

10w30 wont be syn as far as im aware mazda is the only one that makes one for the rotary motors, id stick 2 a fully syn 5w40 or 10w40.

[Guest]

15,000km? huh maybe a new bmw or something of that sort. but a used subaru nah ah

[Swindog]

Even 15w40 from the Castrol GTX Modern Engine is ok. Its turbo tested and been around for years. Very reliable oil, normally cheaper than Magnatec.

same, I ran Edge 10w60 in my old engine and the guy who ported my heads was supprised with how little wear I had on my lifter buckets. He said to make sure I keep using the same stuff.

It'll be going into my new engine too.

A VERY simple explaination is...

The first number is how the oil behaves when cold (lower number is thinner so moves through engine better when cold)

The number after the W is how stable the oil at higher temps, most people recommed at least 10w40.

Thats because the cam buckets are very wear resistant, all the wear is in the cams.I've torn down engines with 300,000kms, and the buckets show no sign of wear, but the camshafts are shot.

ohh and I use valvoline dura blend semi 5-30w, I wont use any castrol engine oils after the full synthetic fiasco .

What brand of oil does a subaru dealer supply?

Normally Castrol Magnatec

[mondo]

So the subaru branded oil is castrol , or do dealers just stock castrol?

[Swindog]

Subaru reccommend an oil thats made by Castrol.

They dont specifically say to use Castrol but all the subaru mechanics and workshops ive been too have used castrol.

[T.Rev]

Using ELF 5w40 I think

You sound like a conspiracy theorist to me..

[xsvpwr]

The silver 5L oil packs Subaru sell have Castrol on the back
