I buy my full synthetic oil at Menards when they have it on sale and an additional rebate is included.
I usually pay no more than $2 a quart.
I'd never pay $6, $8, $10 a quart for oil.
"FULL SYNTHETIC" for $2 please post a pic of what you are referring to.
My stock of oil is dwindling and I have no diesel oil on hand but that could change at anytime.
I was getting to the point of being obsessed with buying oil and had to back off a couple years ago. :B
Menards doesn't advertise oil being on sale you just have be there. When sale priced it's $2-$3 off a quart and if manufacturer has a mail in rebate offer, Jackpot!
These guy find great deals on oil too.

I picked up some Havoline synthetic oil in a box at WalMart recently. I think that it is special introductory pricing but it was $14.97 for 6 quarts of standard oil and $15.47 for High Milage. Both are for gas engines, I did not see diesel at that price.
Personally, as for rebates I would take fifty cents on the dollar cash for most rebates.Perrysburg Dodgeboy wrote:

I ran nothing but Amsoil in my 2004 Cummins running 25,000 mile oil changes and 10,000 mile filter changes. At around 110K I took it to the Cummins shop next door to the Ram dealer in Maumee, Ohio to have the lifters adjusted. The tech came and asked me how many miles was on the truck. When I told him he said it looks like it is brand new.
Now note that I was running 25,000 mile oil change intervals and according to my oil analysis I could have gone longer. So his idea that it is not worth the price is kinda only true if you are dumping your oil at the 7,500 to 10,000 mile mark.

Lol.... the tech that adjusted your valve lash could not havelooked at the miles on the dashboard, but had to ask you!

I've asked my cousin which brand he and the other diesel techs at the shop run and it was basically the conventional oil that the dealer sold
Yes Troy he did. The service manager pulled my truck into the bay not the Tech. Anyone that thinks Dyno oil is better than full syn is a moron! Or a greedy Tech trying to get someone to change their oil every 3000 miles. So which one his he Troy?
That's hard to believe Don.
I never said which oil is better but I would like to see your statistically significant data to support your claim.
"He" has over >350k miles on his diesel so I would consider his experience more significant than yoursCummins12V98 wrote:

Actually doing oil analysis, as shown above, shows that oil is good for much much much longer than "opinions".
Just got mine back. I was a little worried as I left the oil in the engine for 14,227 miles (and over 3 years!). Oil analysis looked about like you see above, my oil was sooty but still had a TBN of over 7 and could have gone another few thousand miles. The oil was Rotella T6 5W-40. Filter was a Fleetguard Stratopore.
I won't let it go that long next time (prefer to change it around 10k), but the data speak for themselves. It was not only fine, the oil was protecting the engine just as well as when I poured it in.
I did mutiple oil analysis on my 04.5 duramax and now on my 15.5 duramax. analysis when the oil life monitor said near 0%. Usually around 7K miles. In EVERY case using conventional oil analysis showed TBN still high and other indications recomending I could easily go 10-15K miles between changes.
I've done the same thing on my 2 1997 cars, 7500 miles conventional oils, TBN high, no contamination, again, easily go to 10K or more.
New oils and new engines are far better than the days of 3K or even 5K oil changes. At least on GM and my european cars, the oil life monitor is EXTREMELY conservative on oil change intervals. Follow it and do an oil analysis and I suspect you will find the same.
One car is now at 190K miles and uses maybe 4 oz in 7500 miles, 04.5 Duramax is at 180K and also uses maybe 4-6 oz of oil in 7500 miles or so. 15.5 is only at 45K similar.philh wrote:

I just had my oil changed at the Ford dealer (first 3 oil changes free because I bought it there) and when I picked it up, the service department manager told me that I was good for 3,000 miles or 3 months. Talk about selling service where it is not needed. The F150 owners manual says to change the oil according to the on dash display, or one year, or 10,000-whichever comes first.
I think that I will go by the Ford engineers recommendations. I do shorten those numbers up a bit, but not by much.
That’s what Ford wants. You go by thier “recommendations” and you will be buying a new truck sooner!
What I find funny is the amount of people that use the manuf tow ratings and deduct a percentage for safe towing, yet when it comes to maintenance they throw the recommendations out the window and push the maintenance as far as possible!
My wife's Edge Sport runs Motorcraft Semi Synthetic at 10k mile intervals via the OLM. Looking thru the oil fill port the cams and all surfaces look shiny new at 68k miles. Her previous Edge had ~100k miles using same oil and OCI with the same excellent results.Ozlander wrote:

Probably because they got it for nothing.
No... they get it at a discount. Point being these guys don't pay the extra money for a boutique oil.- I change the Oil and filter every 5k miles, very easy to keep track of.
