On the other hand, today I drove my 2007 5.4L 3 valve Ford truck. I also put QS FS 10w30 in it in April. It’s noticeably quieter. In my head or not. I’ve put 225,000 on this truck and hot idle has always made some valve train noise due to cam phasers and whatnot. This truck is smooth and...

Yes it’s a TGDI. I haven’t had a 5w30 sample come back in the 30w range ever. I was trying to see if a 10w30 would.

Why stay away from HM? I would like to stay with the QS FS because it’s cheap and local. We’ll see how it dines at the end of this service.

I recently (500miles ago) changed the oil in my commuter car 2018 Ford Escape 2.0 with 75,000 miles on it. I was using some Castrol Edge High mileage 5w30 and noticed nothing out of the ordinary. Nothing good, nothing bad but did get Slightly higher fuel mileage than with a the previous change...

Got two of these to try running a 10w30 in my ecoboost.

2005 Kia Spectra 183,274 miles on car, 3,274 miles on oil. Out- ST 9688, Chevron Supreme 5w30 In-

Its an inherent problem with direct injection. There is no fix. I’m not trying to fix anything. I’m trying to prolong my engine life. Would you not agree that if I ran an oil that actually stayed in the specified grade through an OCI that the results could possibly be less wear on internal parts?

Which is why I’m researching and looking for answers as to which oil will stand up to fuel dilution better. A 10w30, 5w40, euro 5w30 who knows. I’ve got a couple of UOA on the forum showing my diluted used oil. I’ve use QS full synthetic 5w30 before but wasn’t able to sample at the time. On...

Not that I know of… I’m having a problem keeping an oil in the 30w range for 3,000 miles with this car. It’s a TGDI 2.0 and it will turn a 10+ CST at 100c to a >8.6 in 2,750-3,000 miles. This run is Castrol Edge High Mileage 5w30. I’ll sample at 3k and see if it shears or fuel dilutes to a 20w...

I have no idea. I was lost at hydroisomerized. Is that a lesser grade than a group 3 product?

What about Havoline Lifelong 10w30? CAS number 72623-87-1. They say it's a C20-50, hydrotreated neutral oil-based

It’s Castrol Edge High Mileage 5w30. I did a VOA and it didn’t look very impressive on paper. I’m going to run a UOA at 3k miles and see where we’re at with it. Want to see if it’s worth the price.

I see folks here reading SDS to determine the type and amount of base oil in the final blend. I’m not fully understanding how you are doing this. I’m posting a picture of the current oil in use in my car and wanted some help figuring out what it’s make up of. I thought it was 50-75% group III...

changed the 5w30 out at 8-9 hours. It wasn’t low but it was dark. Not black but definitely darker than it should have been. Filled it with the 30w and ran it until the carb ran dry.

I picked up a quart of sae 30 to change it out when I put it up this time. Thanks.

I have a GP6500 Generac generator that is air cooling. My power will be out all day and the power company advised us to plan for an outage while upgrading in happening. I pulled my standby generac out and checked the oil. It was due for service so I fired it up to warn it and drained the oil...

Looks like they are owned by Premium Guard now

Seasonal service on my sons John Deere Gator. Not paying $12 for a Premium Guard filter in a John Deere box at the dealer.

2021 Cfmoto Zforce 800EX 450 miles, 53.3 hours. Out: Valvoline ATV/UTV 10w40 and Cfmoto cartridge filter In: Castrol Power1 10w40 and HiFlo cartridge filter

Not sure. I’m considering QD full synthetic 10w30. I was to pull a sample of this Edge HM in there now at about 2800-2900 miles to decide if I should stay with that instead. That gives me time to shop before I have to change it.
