Delo 100 30wt

[chevman4life]

Just picked up a gallon of DELO 100 30wt today at a good price. I have used 30wt before in my old Chevy but was wondering about the 100 series with it saying "for 2 cycle diesel engines" on the front. What is the main difference in this and the DELO 400 30wt? Thanks.

Big difference. It is low ash, low detergent, low zinc. Designed specifically for 53 and 71 series Detroit 2 strokes. Not for 4 stroke anything.
Now Delo 300 - that is a different story.

I'm not able to find much info about Delo 100 online. What kind of issues would there be if used in gas 4 cycle. Just curious.

Here's the data sheet for Delo 100 40 wt; the 30 weight will be identical except for the viscosity data:

Basically, it is an obsolete oil for obsolete engines. If you have an emergency and must add oil, your Delo 100 30 will be better than nothing, for sure. Otherwise, I'd use any gasoline engine 10W-30 before I'd use anything else in your Chev.
