Its 15w40. Or is this oil for the new multivalve engines.

Well I need to know if I can use it on a 2F Engine.

Of course you can use it. Its more important that your oil is clean than the brand or type (other than Pennzoil, which is pure wax based crap). (and needs to be ase approved detergent type) Synthetic oils have a more uniform molecular structure, (think all ball bearings). Regular oils can have odd shapes at the molecualr level...the "balls" move around easier than the other mismatched shapes. Synthetics are expensive, up to you if you think its important enough to spend the extra cash. Opinions vary...we'll see what everyone else has to say.

Well Its Semi Synthetic 15w40 oil. The people here in venezuela said that type of oil would damage the engine.

Or can I use Full synthetic oil. Because Castrol is the only Synthetic oil that they have here.

Castrol makes good oil.

 

[weak-link]

does it say "oil" on the can?

If it does then I'd use it. If it doesn't then I wouldn't. I've used gear oil with no ill effects, engine was already on its last leg.

Use Shell Rotella T 15w-40

If you have any leaks at all, running synthetic will amplify them.

yep

And yep

So true!

It's a Land Cruiser. Mazola cooking oil will work.
Expensive synthetic oil will just leak out faster. Use whatever you can get cheap, change it twice a year w/ a good filter.

Hate to disagree with Lord Jim, but modern oils have eliminated Zinc Phosphates due to environmental reasons as well as reactions with CAT converters.

Fine for roller rockers and modern engines, but not-so-good for old faithfuls .

Or, Jim, do you think it really doesn't matter in these motors (2Fs, etc), 'cuz they're low-reving?

I wouldn't use synthetic, btw, just Rotella T

My opinion is that new, US EPA legal spark ignition motor oil is death for a fresh 2F.
Without the zinc, the new, soft cam will eat the new, soft lifters.
But once the cam & lifters have hammered on each other for a thousand miles, then they should be surface hardened adequately to withstand the crap oil we get here in the US.

That being said, I run the cheapest diesel rated oil available, 15W40 CarQuestoline Fleet.
But I still think Mazola (or maybe Wesson) would be OK in a pinch.
