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.

I needed it to mix with 5w40 Lexus oil and it worked really well. I had some valve noise from previous oil but when I bought this it's gone. I'm using three 5W40 and 1L of this in my 2000 Camry which has around 420,000 km on its odometer. Cold start in the morning has also improved to have less noise as compared to before.
