Sae 30 for 99 Isuzu?

[SC Maintenance]

Those are reputable. I was just thinking that it’s such a rarely used product that hardly anyone would make it. I think that a higher quality 5w30 would still be a better option though.

Then you get into defining quality

I just did my lawn mower oil change with some Valvoline SAE30 I have had around for quite some time. When I run out I will go to 15W-40. However I only use maybe a quart or two a year at most.

I know with my 97 Rodeo the HLA's would start slapping away with 10w30 and the recommended fix was Mobil1 0W30. Strange that they would still be recommending a thicker oil after they discovered that particular problem. Far as I know those were powered by the same 3.2 weren't they?

If the Mobil 1 0w30 was the ESP, it's actually thicker with a higher HTHS and kv@100C than practically any of the ilsac rated 10w30 oils available.

You don't think it would take too long to pump up to the cams?

No, not at all. Its not that different than a 0w-30 in your climate.

Incidentally I used SAE 40 in my Chevy truck for years and years and the truck loved it.

This was waayyy back before there were different versions of M1.

Is there even a decent straight 30 out there from a reputable company or are you stuck having to get a “dollar store” level of quality?

The ones I see here are "sp" rated.
