Castrol 5w30 V 10w60

[monga]

Recently being using 5w30, but considering changing to 10w60?

opinions

also, motors new

[subie]

W60 is too thick

what he said

[rev210]

I like the castrol R 10w-60.

[Roy]

For a daily driver perhaps the 10W60 Edge could be seen as being too thick. But if you drive the car hard or do track work i dont think you can go past it.

W60 is too thick

Beeing using 10-60 Edge for 3 years.

Never an issue.

If the motor is fresh/built - i say go for it also

[D_Stirls]

The 60 is when the oil is cold and you want your oil to be think on cold start to protect the engine from wear. is more the smaller number that is inportant because that is the thickness when hot which is what your engine spends most of it's time being. If you look at what nissan suggests for our climate and they recomend 10W-30/40/50. For 5W-?? the climate they suggest for this is around 10 degree max. If i was on my computer i could post the chart up from the manual, i can do it later if people are interested.

Me too !

I think its a fantastic oil did over 3 kms at low RPM and no oil pressure i could see on the gauge, turned out bearings and crank was still in good shape and i can only put that down to the oil

[abu]

Also use 10w60 and its better than anything else I've used

[NYTSKY]

Motul Chrono 300V is what ill be using after i run my motor in.Great stuff.

I think you have that totally backwards.

The lower number is how the oil acts when cold (in the case of a 10-60 weight oil the oil acts as if it is a 10 weight oil (thin) when cold.

The higher number "60" reacts the same as a 60 weight oil (thick) when hot.

All engine oils get thinner when hot, so the oil will not be physically thicker when hot.

When cold you need a light oil to move from the sump to all the parts that need the oil to lubricate. In a freezing temperature climate ie Canberra in Winter 5w engine oils assist in starting the car and limiting engine wear.

Most of the engine wear on a normal car occurs at startup where there is limited lubrication.

Better re-read that chart.

[chiksluvit]

there are a lot of great oil on the market..

motul, elf, castrol..

edge is definitely awesome, 10w60 is a little thick for street like roy said though

plus its winter now

Yep sorry i have the numbers around the wrong way;

But here's the chart;

+1 for 10w60. Great oil for my climate.

Willall Racing used it on my motor after it was run in, following rebuild in 2006.

Has been used on my motor ever since.

[Roy]

Those saying its too thick, what does beign too thick actually mean, i mean what do you think the negatice aspect is?

I am happy to sacrifice what, 1-3hp for very healthy oil pressure and stability at high temps.

[discopotato03]

The 10 or 10W is not a viscosity its a cold pouring index . So 20w50 is not 20 weight oil when its cold .

Synthetic oil is supposed to be quite "thin" when it's cold like very cold and this would be a huge advantage at start up .

Plenty of people like the Edge 10w60 but if the 60 number scares you Mobil do a synthetic 15w50 from memory .

If I was pushing a turbo engine hard and for any length of time I'd use the 10w60 too .

I That chrono gear...... Stuff castrol. Motul all the way.

[Sydneykid]

We only use Castrol lubricants in the race cars and all of my Skylines (and Stagea) run Edge 10W60, I have never ever had an oil related problem with any Castrol oil.

The reality is that any of the high end oils today are well and truly better then what was used when these cars were new so pretty much all synthetics will work fine as long as you choose a sensible viscosity
