Is the new Havoline GF-4 a synthetic blend? I'm currently using Motorcraft syn-blend 5W30 and if the Havoline is,ide like to use it too.
Havoline GF-4 question

I doubt it, considering how Chevron touts the abilities of their group 2 oils to meet GF-4 more cost effectivly.
It's a Group II+ base oil. Motorcraft I believe uses group II and III oils, which by most here isn't considered a Synthetic blend either. Both are good oils. I wouldn't worry about Havoline, it looks pretty darn stout to me. We should see some UOAs coming in soon.

I think if you were a fan of the performance of Chev/Hav, GRP II/II+ , GF-3/SL oils, nothing in the GF-4/SM formulation should make you change your mind.
If we can trust the lone GF-4 VOA posted for Havoline 5w30, higher levels of calcium & boron along with the expected drop in zinc/phos, are the only real changes.
The additional boron will help with both the GF-4 oxidation & oil thickening requirements, and aid in anti-wear along with the higher calcium.
This is a good baseline oil for GF-4, as the performance should be fairly predictable compared to some of the new formulations that, to-date, have displayed rather thin add packs in UOA/VOA's.

As I've mentioned before, SM/GF-4 Havoline has a fraction MORE ZDDP than GF-3. Look at their data sheets; the VOA backs this up. I think oil makers have been blending GF-4 levels of ZDDP in their GF-3 formulas for the last year and a half at least.
Don't the 10W-30 oils generally perform better in this regard than do the 5w30?
It seems like 5W-20 vs. 5w30 has been debated on this forum to death, yet very little is said about the 5w30 vs 10W-30 decision.
For mild or warm climates, especially in the summer months, 5W-xx conventional oils seem like a poor tradeoff to me.

Ok,help me out here; I switched from Chevron Supreme 10W30 to Motorcraft 5W30 syn blend.But,being I live in Florida,I should have stayed with the 10W30? Dang,i'm so confused!

From what I see the 10W-30 Havoline thins out also if you look at uoa's. Not sure there would be much difference either way. Most Starburst 5w30's and 10W-30's seem to do this in "easy on oil" engines
M1 and GC seem to hold grade well in non-stressed engines without thinning or thickening too quickly from oxidation.
I liked regular Syntec 10W-30, but switched too, because of this. I think it's a designed in feature.
I wouldn't lose sleep, especially since it's wintertime (even in FL). If it was me, I'd still use a 10w-30 in the summer just for piece of mind. The 10w-30 motorcraft (even not being synthetic blend) is BEEFY.quote:
