There are C3 oils that are also C2.
Based it on my experience with my 1984 Isuzu P/U. Back when it was new, I used 10W40 on summer and 10W30 on winter. If I used 10W40 on winter, the vehicle starts at a slower rate, like the battery does not have enough cracking power. Compared that to 10W30, the vehicle starts immediately. Also, I noticed on winter, when using 10W40 especially when engine is cold and drive it right away there is a drag like it is pulling something from behind. And also, I got terrible gas mileage at 10W40 on winter.
Before Volvo, i owned Land rover discovery sport 2.0 d and factory oil was C2 0w30. But with that Castrol Magnatec car runed smoother and quieter. It was also Euro 6 , practicly same modern diesel like Volvo Spa. I dont understand why is land rover using C2 oils and Volvo C5 oils. Whats the big difference between C2 and C5 oils. i think C2 0w30 should be better than 0w20 C5 or I am wrong?
Quieter doesn’t mean anything. In Europe Magnatec is positioned lower than Edge in Castrol lineup.
INA SINT? Jesi li ti mozda iz mojih krajeva?Quieter doesn’t mean anything. In Europe Magnatec is positioned lower than Edge in Castrol lineup.
C5 is more fuel efficient. That is only reason why they are using it.
Or use INA SINT

In fairness, if I used 10W40 on summer I get the same gas mileage as 10W30 on winter. This is based on my experience on this vehicle.
The oil I used on my other vehicles. my Escape is 5W20 & Jaguar is 0W20 are all year round. If I use XW30, I could get a different result but I "may" not feel the difference in engine performance but for gas mileage it surely will take a beating especially on winter. As the old saying goes, "Your mileage may vary"
It is, isn't it?
I didn't realize 10w's could be so different?
That's a nice improvement!
Oh, I didn't realize that was 1984. Oil has improved since then, right?
I haven't seen anyone yet on BITOG quote themselves and respond to their own question with another question. I guess there is a first time for everything...

I'm not here to make debate or an argument. My reply to Rod Knock's comments was based on my Isuzu 1.9 gas with Carburetor engine. The consistent slow startup cracking and drag I noticed on a cold winter days using 10W40 only happened when the engine is cold, once it ran for about a mile or 2 it runs normally. Also, I am using Conventional motor oil not Synthetic. On the other side, if I used 10W30 on hot summer days, I could have fried up the engine especially here in Texas where it gets to 95+ dF. To be honest, this vehicle has the original engine, only opened during valve adjustments, No knowledge about the miles on it. Odometer stopped working at 99K m iles 30 some years ago.
Get some Mobil 1 FS 0W-40 for your Isuzu and your engine should be happy year-round without any issues.
I have several qts of bottles in stash 10W30s & 10W40s (conventional) that I bought on clearance/discounted over the years plus HM 5 gallons in variants. The thing is, once I got low on my supplies, here comes another clearance/discounted bottles from different Auto Shops.
