I got an 1987 Toyota Land Cruiser with a 2H diesel engine. I never changed oil on a diesel engine prior to this truck, so I'm a little confused.

Toyota Factory Shop Manual recommend API CC oil type, previous owner told me that he always put synthetic oil, and considering that I live in a northern territory(Canada) who have temperature below the freezing point, what kind of engine oil should I put into this engine?

In my other cars, I put regular 5w30 oil.

I agree with calling the local Toyota shop and seeing if someone in the service dept will help you out. If they don't help you then I know that at the winter temps you see 0w40 is what everyone I have ever talked to or read on other forums run in their diesels in your region.

I've gone to 2 Toyota dealer and they did not see any Land Cruiser for years, so they do not know. I found some info in one of the Owner manual, and yes you are right, 0w40 is recommended in colder temperature. – Gabriel Mongeon May 17 '11 at 12:06

Besides the weight, be sure that you buy oil has a "C" code in the service symbol. The "C" indicates that the oil was formulated for a diesel engine; gasoline engines use an "S" code. The top half of the ring should say "API Service C-something". Note that you can have an oil that works for both.

The logo looks like this one:

Thanks, I'll make sure that the symbol is there! – Gabriel Mongeon May 18 '11 at 14:33

call your local toyota dealership and ask them. Over the years, they may have changed their recommended fluid types.

O/P mentioned that he called earlier but they didn't know. I know that some of the diesel guys like Shell's Rotella T6 formula. Check this out:… – Dude318is May 23 '11 at 20:19
@Dude381is: This it what I finally bought: Shell's Rotella T6. And after 2 months, I have no complaints. Thanks for the link – Gabriel Mongeon Jul 4 '11 at 15:37
