OK I'm thinking on trying once Quaker State synthetic "Q" and was wondering how you all feel about this oil???? Currently I'm using Mobil 1 so in comparison do you consider "Q" just as good as M1???
That response told you more than you think. Try each oil, as oils perform differently in different engines, and let a UOA tell you which one works best in YOUR engine.
Thank you guys/gals for your replies. This is what I wanted to hear from you all.
In either case I just bought 6 quarts of the "Q" in 5W-30 weight and will be trying it out in my 4.7 engine pretty soon. If it works out then I'll have another good oil to refer too if my main oils not in stock.
So far I've used/tried 2 others so far (M1 and Valvoline) all synthetic and they work well in my Durango 4.7.
IMO, many oils are 'better' than M1 if we're talking about common viscosities of 5w-20, 5w-30, 10w-30.
If we switch to the other viscosities, 0w-20, 0w-40, 15w-50, Mobil1 fares better. M1 0w-20 SM doesn't have the top-shelf showing that the SL product had IMO.
I'm just not too overjoyed by much of M1's product line anymore. PP, Q Synth and similar Group III competitors seem to have closed the gap from SL to SM spec.
I've been a Mobil 1 fan since they pretty much introduced it in California diring the late 80's years. I've used it in my 89' Camry pretty religiously and I'm happy for the results it's given me since then. Currently my Camry 4 cylinder has about 230K on it and seems to be happy with this oil medium since I can get it from my local Toyota dealership. In my Durango 4.7 V-8 getting/buying that 6 quarts of M1 is getting to my pocket book due to the high gas prices here in Los Angeles where the highest price for gas is $4.20/gallon for Shell!!! With this in mind I need to consider saving a few bucks for my truck/SUV and the Quaker State "Q" is just a few bucks lower in price compared to M1. If the "Q" works out then perhaps I'll strongly consider using it as a standard in my truck.
Since bought new I've changed both car/truck by the book regardless of how much life is left in the M1. For the Toyo it's about every 3500 miles and the truck it's every 3000 miles.
As far as filters go I use the factory versions as I take mine in to the dealership cuz our complex doesn't allow me to change oil on the premisses.
Most any oil SM/SL "dino" will last 5,000 miles with excellent results I do not see how running the Quaker syn oil for 5,000 miles will provide any usefull information. You are fooling yourself thinking there is a benefit running syn oil at your oil change intervals.
Not only is QS synthetic cheap its great oil. I havent tried it but Ive used their dino plenty of times to know they make a quality oil. $19 vs 21$ is not going to save you a lot of money but you can get your oil and 4 tacos at jack in the box with QS.
