I thought about trying mobil 1 esp 0w40 but at the price i might as well use redline. Esp.x3 0w40 would be nice to try to as its a bit thicker than the other 2 0w40 m1 oils
i believe the edge 0w40 is probabaly the better oil when compared to fs 0w40
what are your thoughts on edge vs edge ep?
Once you go past the Mobil 1 products you can find at Walmart, their stuff gets really expensive. Mobil 1 ESP X2 0W-20 is very good stuff and excelent for a lot of small vehicles, as it carries an MB229.71 approval. But it's hilariously expensive. Castrol EDGE EP 0W-20 carries the same approval and you can get that one at Walmart.
EDGE vs EDGE EP: as far as I can tell, the entire EDGE EP lineup has the same additive system as the EDGE EP 0W-20, and theoretically, they could all get that MB229.71 approval, since even the 5W-30 has a HTHS of 2.9. I use 0W-20 in my brothersl's 2020 Sonata and 5W-30 in my 2018 Santa Fe. It takes at least 3000 miles for it in the Sonata do barely leave any dark marks on a shop towel when I check the oil level, and about 1500 miles in then Santa Fe... That awesome GDI soot.
I believe that Castrol cuts some corners with the regular EDGE. In the past they used a different additive system in the black bottle EDGE. Some recent UOAs shiw that it's the same additive system now. Knowing Castrol, I wouldn't put it past them to sell the same stuff in both product lines, bit I don't know that for sure. For a out $3 per 5 quart jug I just buy the EP.
I only tried Castrol EDGE EP 5W-20 in the HEMI once, and it was just as loud as with Mobil 1 EP 5W-20. These are thin oils that don't belong in a HEMI and don't have an additive package for an ancient pushrod engine. Stick to an ACEA A3 oil, that's what I do.
As far as EDGE 0W-40 vs Mobil 0W-40: The HEMI ran smooth on both. The only difference eInnoticed was some oil consumption when towing with the Mobil 1 0W-40. But hey, I scored six 5-quart jugs of Castrol EDGE 0W-40 for $99, so there is that. So I got plenty of it now. I think I got like 16 jugs total, I have to recount them.
Castrol kept busy in the past couple of years and updated their formulations. I think that SOPUS has the messiest product lineup currently, as they keep moving stuff around. Any decent Mobil 1 product is expensive and hard to get. Castrol is the most accessible and offers a whide range of products that you can actually buy at a reasonable price. Their 0W-40 is made in Belgium for example. Their 5W-40 was just updated recently, and they have a 5W-30 that's an ACEA A3 oil that you can buy at Walmart. My dad has always been a Castrol guy, and he was never pasionate about motor oil. He just used it because it worked well for him.
Before I forget: throw a bottle of 15oz of Lubegard in there to clean out your HEMI. Just to make sure you don't have any metal flakes stuck to anything..if anything, Lumbegard cleans well, but you have to run it for a few thousand miles for it to do it's thing. You might even like how it looks and smells, lol. When you pour it in a 5 quart jug and mix it with fresh oil, it turns the oil to a blue-greenish color, it's unreal.
