Just recieved my quart of LE1605 from Hardtopguy, and I'm a little confused about it. I've used LE607 for a couple years now, which was a 90w. I noticed on the 1605 bottle that it says SAE 110... so it's a 110W, correct?

Just curious if this is going to be ok. Any help would be great! Thanks!!

 

it will be fine, it's all due to the newer SAE ratings.

 

It is what is is: SAE 110 (not 110W)
Just like LE-607 is SAE 90 (not 90W)
RadioZero is right: SAE changed the ranges and thick SAE 90 (what LE-607 is) is now called SAE 110.

 

Thanks for the replies

 

This is good clarification from Spitfire. Also, the oil industry uses numbers to identify viscosity classifications as ISO VG, AGMA Grade, SAE Crankcase, and SAE Gear.

The only time they use the letter "W" (reserved for so to speak) is for winter grade characteristics of multi-viscosity crankcase and gear oils. Those would be for the crankcase: 0W, 5W, 10W, and 15W. The winter grade gear oils characteristics are 75W, 80W, and 85W. All the other SAE gear oil and crankcase oil viscosities are listed just as a number because they didn't meet the industry cold standards for labeling as a multi-vis grade. So when you see a bottle labeled with 10W-30 or 75W-110, the 10W and 75W tells you what that lubricant's winter (pour point/cold cranking) viscosity characteristics have met via certain testing parameters.

So, the bottom line is that W stands for winter, not weight as it relates to lubricants.
