Does this Oil suitable for 1999 chevy silverado 2500 186000 miles?

I have been using full synthetic oil in my 98 Silverado 5.7. I now have 364k miles with no engine issues at all. I'd recommend it for anything that takes 5w30

Does the Castro 5w-50 SPT meet the Ford spec WSS-M2C931-B for the GT 500?

Castol says it meets the spec, and Ford SVT has approved Castrol 5W50 for use in the GT500. I use this oil in my 2013 GT500.

is current product dexos 1 approved. I see it on the quart, but not on the 5 quart and wondering if it is an old picture

"Approved - GMdexos1™ supersedes GM-LL-A-025, GM6094M and GM4718M" This is indicated on the 5W-30 Castrol Edge High Mileage data sheet, dated 09Nov15. On their latest data sheet dated 20Sep17, this approved statement is no longer indicated. 1 quart size or 5 quart size makes no difference. If the product was made after 20Sep17 then it is not likely to be approved for engines requiring dexos1. I would safely assume the bottle labeling will reflect whether or not using this as a suitable substitute over dexos1 type oil is acceptable. The picture is old and will, or should, be changed so their is no confusion.

I ordered this and it came with the letters SAE in front of the 5w-30, does it matter?

SAE refers to the grading system. There are actually thicker Euro 5w-30 oils, but this is a thin 5w-30 for American and Asian cars. This particular blend is the latest additive formulation for GDI / turbo engines, it should be one of the best products on the market.
