Oil grades in low temperature use?

Guest
I=B9m going to be in Sweden in February / March with the =8CCruiser and was
wondering what the best grade of oil for the low temperatures would be? It=B9s
a petrol engine, the 1HZ-FE 4.5 24v
It gets down to =AD35 at night, apparently and I can=B9t help think it=B9ll be
like treacle next morning....
My first thought was a 0-50 SAE, but then wondered whether synthetic, semi
synthetic etc made any difference?
Best wishes at Christmas,

Hi Neill,
My pick would be Amsoil 0W30 (you can use it as a direct substitute for
10W30) it hasa pourpoint of below -60?C so even at minus 35 your truck
will start and run and build up goood oil pressure fast. It is a very
tough oil I used it in my GT4 Celica that was running 15psi boost and
making big grunt out of its little 2L engine and I used to analyse it
every 10,000km and the oil always withstood the abuse the turbo engine
dished out very well. 0W50 is too wider viscosity band a 30 weight span
is about as far as you want to go otherwise the oil has to be doped very
heavily with viscosity index improvers to create the very wide viscosity
range. After a few km's of abuse the wide band 0W50 will likely shear
back to 10W40 or even 20W30 as the top end breaks down it tend to
thicken the bottom end. I would definitely go full synthetic for it's
improved pumpability at low temps.
Cheers,
Craig.

Thanks for the fast reply, Craig.
Care to share any more details of that Celica? I=B9ve got fond memories of
them...

Neill,
I have read in Toyota literature somewhere not to use oil below
10w 30 if you have a turbo fitted. When I went to Russia I threw out 2
Gallons of 5w 30 as I did not find out before buying it.
Regards, Clive.

Thanks, Clive, but it's the 24 valve petrol engine, so no worries there.
Craig in NZ emailed me off list suggesting Amsoil 0W30, but not sure where
I'll get it in the UK.

Hi Clive,
The Toyota literature is wrong, but there is a reason for it, you can
substitute 0W30 or 5W30 in place of 10W30 as it is the 30 part that
determines the suitability of the oil once it is warmed up the 0 or 5
part relates to the bottom temp you can start in. The reason Toyota on
there diesels does not reccommend 5W30 for sustained use in anything but
quite cold condtions is to do with the quality of typical oil base
stocks used in Japan. They are very volatile in europe most grades of
oil are illeagal for sale if they have a NOACK volatility of over 13%
(basically a beaker of oil is heated to 250?C and a very mild vaccuum
applied to it and left to cook for one hour the loss of oil is measured
as a percentage of mass lost in that time and that is the NOACK
volatility for that oil). Most OEM oils in japan have a volatility of
12-17% so the loss of oil due to boil off in the thinner grades can be
quite high.
As a comparison the 0W30 I reccomended has a volatility of 8.6% a pour
point of -54?C and a borderline pumping temp of -40?C (so if you are
going to be starting in temps below -40 then a sump and or block heater
might be a good idea.
A chepaer alternative is Amsoils ASL 5W30 with a noack of 6.6% and a
pour point of -60 but the 0W30 is there super premium high perfomance
low viscosity oil.
Cheers,
Craig.
