Experience using 0-40 synthetic engine oil

[D7E]

Any body using 0-40 in heavyer equipment , I find starting much easies in -40 temps but is it safe to run in heavy applications in summer too ?

Nice to hear from another Canuk.

I haven't used 0-40 but do commonly use 0-30 in the winter but do move up to the 15-40 in the summer.

I did work for an oil company for a number of years. The 40 identifies how the oil flows once the oil has heated up. So the 0-40 will be excellent.

Be careful about the manufacturer of the 0-40; anything that much of a spread between the two number is very difficult to mfg. It seems like only could be done with synthetics. It if is made by a reputable company then it will likely be good.

All the best

In -40 deg. temps the 0W-40 should work great for you. It will make starting quite a bit easier at those temps.

If it's newer equipment that is still under warranty check to make sure that it is a approved viscosity. If you should happen to have some kind of engine failure and they do a oil sample and find that you are using a unapproved viscosity they could possibly void the warranty. Manufacturers often look for anything to void a warranty on high dollar repairs.

If you're looking for easier starting in very cold conditions, why not just use a synthetic?

If it's a 0W-40 it is most likely a synthetic. You would need to add quite a bit of viscosity index modifiers to a conventional base stock to obtain a 0W-40 viscosity and it would then be very prone to shearing.

Our 2008 Mercedes common rail V-6 turbodiesel specs 0W-40 full synthetic only.

All our racing KTM motorcycles spec Shell Helix Ultra 0W-60 full synthetic though, which is unobtainable in the US unless specially imported!

It's local CO-OP brand but it is synthetic .
I've only tried it in one of my tractors (snow blower) a 82 hp FWA Massey and it is my newest tractor at 1993 most of my big stuff runs 1975-1988 apart from my 1953 fordson major so warrantys are not an issue and my big stuff onlyruns in warm months ( March-September )so i would stick with the 15-40 for these , I just wondered if it was safe to run all year round to save unneccasary oil changes at $92 per pail .

Experience using 0-40 synthetic engine oil

I think that he is talking about synthetic since the thread topic is Experience using 0-40 synthetic engine oil

If I can get 0w-40 Mobil 1 for the next oil change on my 1983 Benz, I'll buy it. I use it when I can find it for makeup oil. If I could get 0w-30 for all my other engines (incl. my JD diesel), I'd buy it. They only offer 5w-30 locally. For the first change to Mobil 1 on the Benz, I had to use a 50/50 mix of 5w-30 and 15w-50 to get an approximate 10w-40. Next 2 changes were with a 5w-40 that I found. If I can get larger quantities of the 0w-40 (lower cost), I'll use it next change.

There's no problem with this wide a range on a synthetic. The lower the first number, the quicker you'll get lube to the upper parts of the engine, and even at 0w in summer, it'll STILL be heavier than probably even 40w at operating temperature.

Your John Deere dealer has 0w-40.
