What is your conventional oil choice.?

[Tony10s]

My favorites: PYB / QSGB / FS

 

[SR5]

Penrite HPR or Castrol GTX or Valvoline XLD

Probably in that order too.

 

[TheExpectorate]

Valvoline white bottle, Pennzoil yellow bottle, or I grab some Supertech if any oil will do.

 

[THafeez]

Mobil Super 5000

 

[gallydif]

Whatever has the rebate going or is on sale. Let's say there's no sale or rebates, my favorites are in no particular order-

1. Chevron Supreme
2. Havoline
3. QSGB

Do tell? $1 each!?!??!!!!

They were clearing it out. Not sure why, but the shelf had a little tag saying a dollar each. So I had the wife stand and guard the shelf while I ran to customer service with a jug to double check the price. Sure enough, $1 plus tax. Ran back and cleared the shelf lol

Smart decision !

 

[53' Stude]

#1. ST.
#2. MS5K
#3. NAPA CONVENTIONAL

 

[Nitronoise]

QSGB for me 275K on my Daughters Hyundai and it still is healthy according to blackstone

Haven't used "conventional" oils for thirty eight years since switching to Mobil I in 1978. Change the oil and filter each spring and fall. Been doing it so long I can't stop. Entropy will stop that in the next few years though.

 

[dgunay]

1)PYB 10W30
2)VWB 5W30

 

[mcgophers]

Valvoline White Bottle or Havoline. I'd introduce GTX into the rotation if the bottles weren't so difficult to read.

That engine in the picture clearly shows coolant intrusion.

 

[Doublehaul]

QS did not cause that

Whatever 15W-40, 20W-50, or 30 that can be had cheapest. Considering that Napa runs their 15W-40 on sale for ten bucks a gallon several times a year, probably that. We are using Napa 15W-40 as our shop oil at the moment. I don't have much reason to buy regular PCMO's anymore.

The last Napa sale on 15w40 I caught it was $8.99/gallon. I bought several it seemed like a steal.

 

[Camprunner]

Formula Shell in all weights for my office fleet of cars and trucks. My cars and trucks get synthetic M1, ST, Napa, Valvoline, although I am thinking about switching all my personal cars and trucks to FS conventional since I really see little difference on cars lasting with either conventional oil or synthetic. Have also had the valve covers off a few cars running FS and all were real clean with many miles.

 

[Indy]

My number one choice is Quaker State conventional.Just bought some on sale today.Second and third would be PYB and MotoMaster Formula 1 conventional which is made by Shell

 

[Kuato]

VWB, if I ever move away from synthetics.

 

[Red91]

Now that you mention it, I believe you are right, and it is usually $8.99 a gallon.
