Yes. There are a lot of details regarding temperature, grade, etc. but yes. Trying to keep it simple the 80-90W means it flows like 80w, (cold weather use) but coats, sooths and protects like 90w (in hot weather). I think for desert, I saw 120w allowed and you can find 90-120 around. Someone can provide you a more scientific explanation if you need it.
Bottom line for my truck for ten years with no problem has been......well...yes. Regards waw
