Have some qustions. Bought the car with 113,000 Kms, and began using Synthetic Oil. Currently I'm using Quaker State Advanced Engine Full Synthetic (10-W30)

I was just wondering if 10-W30 is alright to use.

I live in Canada.

Summer Temps (5-35 Celcius)
Winter Temps (10- (-40) Celcius)

 

I'm using 5W-40 with more than 200,000 KM, no problems.

 

10W30 in the summer months
5W30 in the winter months, a little easier to start when it hits -30

 

How bout this, 5W30 or 10W30 in winter, it doesn't get all that cold here in winter, maybe only REALLY cold for a week at most.

And then 10W40 in summer for a little extra protection??

 

10W-40 is semi-synth oil

 

Im from Michigan and I use 10w30 all year around. If your Using Synthetic, Use Mobil 1. Mobil 1 is the only Real synthetic oil on the Market(well besides Amsoil). All other "Synthetics" are just really refined Conventional Oil.

Heres my own plan. I use Valvoline Conventional 10w30 ,, then when Winter hits,, I mix 50/50 Valvoline Synthetic and valvoline Conventional 10w30... I use valvoline because I won four cases of valvoline in a drawing.

 

i just use mobil 1 10w-30 all year round and am going about 5k between changes and all is well. smile.gif

 

It be nice if you filled in your profile and said WHERE in Canada you live, temps are CONSIDERABLY different from say Victoria to Saskatoon!

 

Ok well i'm just gonna keep using 10W-30 all year. Mobile 1 though. Thanks.

 

castrol 10w-30 all year round. 112k on the odo.
