These thick 30's have a HTHS of at least 3.5: Delvac 10W-30, Delvac 5W-30, Delo 10W-30 XLE, Delo 5W-30 XSP, Rotella T5 10W-30 (has higher Phosphorus, might not be great for the cat if you're burning oil), M1 HM 10W-30, Pennzoil Platinum Euro L 5W-30, Pennzoil Euro 0W-30. I'm sure I forgot a few.
All xW-40 oils have a HTHS of at least 3.7.
Delvac 15W-40 is pretty cheap at Walmart...
