I bought a 2018 f150 with the 5.0 in March. I know that some/many use a lot of oil, so I immediately changed it and used a Motorcraft filter and 8.8 quarts of royal purple 5w30. It had not used any until we drove 4 hours at 75 mph. I checked the level before we left and it was down exactly a...

I have a 2018 f150 5.0 4wd crew cab. I’ve been using 5w30 oil which has helped eliminate the oil consumption issues. However, my son informed me that if there’s and engine issue, that ford could refuse to repair it under the warranty because the owners manual says 5w20. Is that possibly true...

I have a 2018 F150 with the 10 speed transmission. My owners manual specifies LV ATF. However, every site I go to says ULV for all 10 speeds. I know they are not compatible fluids so what the heck do I do?

My wife traded her escape for a 2023 Santa Cruz. Neat little truck though too small for me. Anyway, the owners manual says to use Quaker state 0w20 oil. I don’t care about the brand, but I somehow wound up with 6 5-quart jugs of mobil1 5w20. The oil change interval is 8,000 miles in the...

I’ve been doing a lot of research since my 2020 Edge 2.0 TGDI hit 70,000+ miles. From everything I’ve seen it appears that thinner oil on startup is better for the turbo. So, for winter I’m using 0w30 which seems good so far, but for summer I’ve used 5w30. I’m strongly considering Mobil 1 SP...

I recently bought a 2020 ford edge with a 2.0 ecoboost. I’ve changed the oil with mobil1 5w30 a couple of times and switched to mobil1 0w30 for winter. The owners manual shows this chart: As shown, the 0w30 handles the cold better but I’m surprised that it handles the heat to 104 like the...

I recently purchased a 2020 Ford Edge with the 2.0 ecoboost with 50,000 miles. I’ve changed the oil twice and had the same noise each time. The engine rattles for a good two minutes each time with the little oil can pressure light on. Then quiet and normal and no oil pressure light. I know that...

I’m using Mobil 1 extended performance 5w20 in my 2019 Ram Classic 5.7 Hemi and have oil pressure when hot at 26-27 psi idle and 46-47 psi at 75 mph. It’s low by 5+ psi compared to many folks I’ve talked to. I’ve heard that Mobil1 Truck & SUV is a bit thicker so maybe a few more psi using...

My wife bought a 2021 Bronco Sport with the 1.5L 3 cylinder ecoboost engine. The owners manual specs 5w20. Well, she traded in a Maxima that used 5w30. I found mobil1 5w30 on a great sale just months before she traded. So, now I have 30+ quarts of 5w30 mobil1 that I apparently cannot use. Any...

I recently purchased a new 2020 F150 2.7 Ecoboost. With the direct injection, twin turbos, and the low speed carbon issue, I am surely concerned about the oil bransd and quality that I use. Last spring, I purchased a bunch (30 quarts) of Mobil 1 full synthetic 5w30 (NOT extended formula) at...

I just bought a very pristine 2005 f150 4x2 with a 5.4L v8, and 91,000 miles. I intend to use an FL820s motorcraft filter, but I want to use a synthetic 5w20 or 0w20. I am thinking about Royal Purple, Kendall Gt1 full synthetic, or open to suggestions. The truck is in great condition with no...

I mistakenly bought 7 qts of royal purple 0w20'oil for my new ram. Its specked for 5w20 but I read somewhere t hat 0w20 typically has better base stocks and gives better protection. Based on that info,if correct, I would like to try it. I don't know enough to make the best decision so I'm...

I just upgraded to a 2014 Ram 2500 Hemi 5.7 yesterday. It does NOT have the MDS system. In reading the owners manual, it says: Use 5w20 oil unless GVW is 14,000, then use 5w30. Well, I am over 14,000 pounds with my RV, but certainly at 6,200 pounds without it. Certainly, I am not going to...

I have been using Royal Purple 5w20 in my 2013 Ram 3/4 ton Hemi for the first 8,000 miles. After doing some research (which I should have done first) it appears that RP is a good oil, but highly over rated and over priced. Looking at a lot of oil specs, it seems like Quaker State full...

I bought a 2013 Ram 2500 Hemi and drove it 2000 miles before the first oil change. I had heard a lot of good things about Royal Purple, so I thought I would try the 5w20 as required by Chrysler. Prior to the oil change, I was getting about 15-16 mpg average and got 19.1 hiway. I thought this...

A bit of a quandry.....bought a new 2013 Ram 2500 with a Hemi. Oil cap stamped with "5w20", BUT the owners mamual states to use 5w30 when gross vehicle is over 14,000 pounds. Truck weights 6200 pounds, and our travel trailer is 8200 pounds.....hence 14,000+ pounds. We dont tow all the time...
