I appreciate your enthusiasm for lending help but as I hinted at earlier, Mobil 1 is just too easy for me to get and reasonably priced such that I don't need to look for a better price on something else.
Perhaps your information may help other Canadians who may not have easy access to Mobil 1.

 

FYI, I tried a 5w40 synthetic (in the summer) and will never go back to it.

 

Mike, can you elaborate? What brand were you using?

 

I was using 5W40 Castrol Syn., it was too thick, slow starting/warming and slower engine rev, "harder" to go into Vtec. (even though it is rated 5W it felt thicker at low temp. than 10W30)

 

Is this the new "european" formula Made in Belgium Castrol 5w40 or the old made in US syntec? If in us, that's crap oil, or at least inferior to Mobil 1 and the Belgium stuff.

Xviper, for your extreme cold temps, I'd suggest you run the Made in Germany Castrol Syntec 0w30, it's available at Walmart/CT for $6.66/L Cnd and so far it has produced many impressive UOA's with various engines on bobistheoilguy.com It's on the the thick side of 30 almost a 40 weight. Just make sure it's Made in Germany and has a green colour tinge when you pour it.
If I wasn't storing my S for the winter, that's the oil I'd use all year round.

 

Thanks for the tip. I'll have a look next time I'm in Walmart.

 

Ever since I purchased my S2 I've used the Mobil 1 product for two reasons that have already been stated. Price and availibility vs. the others its impossible to come by and price is crazy. Im already at a $40 oil change doing it myself, some places like Jiffy Lube etc. are charging $50 plus for full synthetic oil changes! I have noticed though even with the M1 in the car I will still use a quart under heavy driving in a 2500 mile span! Has anyone else noticed this with there cars?

 

This is not usual for this car.

 

Xviper what do you think it is then? I rarely drive hard and the previous owner was an old family friend that was always on top of things. Isn't it normal for some type of oil consumption with these cars? You cant smell it and the tail pipes are always clean, never any type of residue!

 

I changed to Redline 10w30 at about 2,000 miles. Used about half a quart in the next 2,000 miles but it was a good, hard 2,000 miles.. tons of VTEC.
