Well, it's been awhile, but I have a question...
Truck (1992 Chevy w/ 4.3L V-6 approx. 90,000) on startup blows out a small "cloud" of blue smoke. Figure it's probably leaky valve seals (use to blow smaller amount of white smoke, but over time, it has progresed and turned blue). After a couple weeks of running, you can see a visible loss of oil level on the dipstick, either from startup or consumption while going down the road.
Anyways, I'm running 10w-30 Pennz. HM now and have not noticed any decrease in smoke or consumption.
Of course, I really like the 15w-40 HDEO's, but the cold-startup issues preclude myself from using them in the cold months (I believe?)
Any thoughts on this?
Thanks,
Justin.
BTW, I have no problem using Mobil1 10w-30, but I believe that with my valve seal issues, the full-synthetic will make the issue even worse.
