I'm planning to use Mobil Super 5000 (dino). Will this be safe for a turbo application, keeping in mind I don't beat the snot out of my engines (not a ton of boosting going on). I was going to run it to 3000m the swap over to a full synthetic oil. Should I be OK to do this? Thank in advance for any insight.
Personally, I am fine using the FF until the first normal oil change interval. None of my fleet vehicles get early oil changes and none have had an oil-related issue, including LE vehicles. I run my personal vehicles til my normal interval as well.
Very few of my fleet vehicles get "fancy synthetic oil" - I kid about the use of the word "fancy". This includes Ecoboost Fords (the 3.5 V6, not the 2.3). Some of those are flogged with LE duty. I have had dozens of vehicles on Dino with 7,500mi intervals. Dino will be fine for 5,000. Dino is darn good and the gap between the two is ever shrinking. The smaller displacement turbo and DI will shorten that oil life but you will fine with only partial hooning it. Sometimes my vehicles get a synblend change (the GM require Dexos when under warranty, go to barrel dino after that) but that is more like a "lucky freebie" than a conscious effort.
The only vehicles I "upsell" to Syn/synblend are some of my transit/shuttle vehicles (Ford 3.7V6 and the 5.4V8) . Because they get 25K miles a year averaging 12.5mph (so 2000 hours per year), doing a severe duty, I just want to change the oil less. A little less vehicle downtime for general PM and the "hassle" of government purchasing (I can't stock up on oil filters or oil like I would like... so oil, tires, and filters are a PITA), I will take it. Nothing like being told to get $6.99 "contract" Valvoline Dino... just shook my head at that. Worse, the NAPA brand was on sale and I could not order it because "NAPA" was not an approved vendor, but National Automotive Parts Association was.
I run Synthetic in my personal vehicles just to reduce the number of oil changes I need to do in a year. That is all of the major benefit there.
