Ikon XD 52 oil change, which oil?

Even better get some Mobil Delvac 15w-40 for about the same price ($15).

SAE 30 will do a fine job but I found my ZT having a hard time turning over during the cooler months when I was running it.

The Delvac doesn't have a gas engine SAE rating. Only diesel engines.

Right and for SAE 30 we aren't even talking about it being that cold. I was noticing slower starts at approximately 60* F. Not a surprise when you look at the temperature range for SAE 30 which bottoms out at approximately 50* - 70* F. Starting your engine in these temps over a long period of time with SAE 30 WILL cause engine problems.

Those charts are about garbage. The temp rating varies depending on which owners manual or in some cases what brand of oil you choose to use. Take 30w for instance. Some charts will show the minimum temp at 50*F and others will show 40*F Your chart shows the maximum operating temp of all the 30w oils as around 100*F but 0w-20 and 5w-20 are operated at well over 100*F everday where this chart shows the max at 90*F

That's what I was curious about, since my manual says 30w goes down to 0 degrees Celsius.
