[Galantspeedz]

both are fully synthetic oil. but shell helix is 5w-40 and mobil is 5w-30.

using shell now and haf about 1/3 bottle left. wants to change to mobil 1.

can mixed both oils together?

 

thanks

[Stivo]

simple terms... Better not cos different viscosity!!

[Galantspeedz]

aiyo den how ar? muz stick to shell all the way ar?

Can drain out Shell and pour in the mobil 1 on your next servicing lor.

[Dwoon]

Can mix lah.....

 

Another way is to change to Mobil 1 and keep the 1/3 bottle of Shell for topping up inbetween OCI.

[Galantspeedz]

okie okie thank you for all ur replies. let me be guinea pig and mix and see what happen

[Dwoon]

Fyi.... I've been mixing quite a fair bit....

 

Mixed 2 quarts AMSOIL 10W-40 with Mobil 1 0W-40..... no problems...

 

Mixed 2 quarts of Mobil 1 0W-40 with Mobil 1 15W-50 also no problem.....

 

All because I had left over. Now I've just bought cxxxxxe and have left over M1 15W-50.... might mix again. But maybe not as I intend to do shorter OCI for cxxxxxe. M1 seems too good/expensive to use for short OCI. Most likely will buy more to make up a complete fill.

eh... M1 4w-30 got someone selling 1 carton (6 bottles each 1 litre) for $60

30 weight is too thin for me... thanks for the feedback. But should you see at least 40 weighted Mobil 1 and going cheap, let me know hor....

[Galantspeedz]

okie no prob. anyway thin or thick got wad diff ar?

[Cyberet]

i intend to mix this for my next servicing

 

200ml Mobil Delvac 15w40

1600ml M1 10w30

1000ml RP 5w20

 

 

dunno any chemical conflict or not

eh... urs sounds more like rojak to me leh. indian rojak or chinese rojak?

[Dwoon]

I cannot use too thin oil as I like to wack my ride. Higher temps are experienced and my oil is usually badly sheared & comes out like water during my 10K oil changes. If using thin oil to start with... if it breaks down further, my engine might not get sufficient protection till the next OCI.

 

Also, thicker oils give quieter running engine at the expense of FC... but I can live with that.

ang mo rojak

 

aiya got left over mah, so mix all in la

 

thick ah.. thick and slimy and gooy

thin is.. thin, water, and slippery

 

galant can use 30wt i think

u running turbo charged car, of course la

 

NA seldom gets so hot unless u track

 

normal driving takes about 20mins for the oil to reach operating temperture

-----------------------------------------------

sounds like something u produce if u do to often and if u do it once awhile

[Galantspeedz]

so means, thinner oil will be abit better FC but noisy engine? i dun really wack my ride so i think its alrite. moreover i always change at abt 7k instead of 10k

 

so galant 5w-30 no problem hor?

[Dwoon]

20 mins for oil to reach operating temp? Wah... so long ah....

 

It takes about 3 mins of slow/easy driving (about 5km at below 2k rpm) for my oil temp to reach about 80 and about 5 min (~ 10km) to reach 90 deg. If wack from cold start (which is not advisable), then I think it'll be much , much faster.
