After scouring through lots of threads here about oil preferences, I decided to switch mine to Rotella 15w-40 with a fresh Mobil 1 filter.
I'm a bit of a neat freak so I always clean and wipe up any oil splatters after an oil change. Typically, that's on the block where the filter is, on the frame/suspension underneath, and around the valve covers.
I drove it the next day for about 75 miles round trip and noticed a really nasty oil smell from the engine on the street as well as on the highway. Cold and warm engine. As if oil was burning somewhere. I just replaced the valve cover gasket and o-ring on the distributor and checked to see if those seals were still good. No evidence of oil leaking in those spots. No smoke that I could see from the engine bay or tailpipe. Couldn't find any new-looking oil leaks either. Double-checked to make sure the filter was seated and flush.
This nasty oil smell went on for a couple of days to the point where I couldn't drive it anymore. My buddy and I went surfing and even he commented that it stunk. It never stunk before I switched to the Rotella 15w-40. I suspected it was the new oil so I switched to Mobil 5w-30 Synthetic I had at home for my 1st Gen 4R and yet another brand new Mobil 1 filter. Drove it the same as before and there is no smell at all. No leaks.
Anybody else experience the same nasty smell switching to Rotella 15w-40 or any weight change for that matter? Still wondering if there was anything going on internally for the engine to burn more oil with the 15w-40. Or if other oil types burn just as much internally, but just don't stink like 15w-40 does. It's totally possible I missed an oil splatter somewhere that slowly burned off, but I find it unlikely since I spent a lot of time cleaning up after the initial change.
