Oil change interval, synthetic or no, curious what we all do

[JASinIL2006]

Do you guys really believe that stuff came from decomposed dinosaurs? Or vegetation?

Plants, algae, plankton.

Under enough Pressure/Heat/Time it is very possible. Natural Gas is found in great quantities deep underground, and it comes from things decomposing.
Coal is comprised of Layers of what resembles pressed Vegetation

Takes 15 mins to do a drain and fill in my driveway. Mobil 1 Synthetic . I aim for 7-8k , but have stretched it past 10k. OEM filters are cheaper at my dealership vs aftermarket.

I have the re-assurance knowing that it's done properly , using quality oil, at the right levels . And that no teenager , or druggie , or bottom of the barrel loser who's failed at everything else in life is going to destroy my engine at one of those quick lube places.

Yeah, "5min or less", or some such. As if such a claim would make me want to go there. No, no, please take your time and at least do it right. I had it done at WM once on an old POJ truck because I just didn't feel up to it. Got the cheapest oil (Quaker State) and I don't think they made any money on the deal.

I always get the Warm Fuzzies when I can buy something and the seller takes a loss.

Synthetic oil vs. regular oil is an ongoing daily discussion/argument across dozens or hundreds of websites. There is no single correct answer. Rather than over think this and argue back and forth, the best approach is to simply follow the recommendations in the owners manual. Just follow the manufacturer’s recommendation regarding type of oil, viscosity and change interval. You cannot go wrong by doing that.

I just do what my truck tells me when it tells me, via the dash reminder. Other engines like OB, ATV, lawnmower, once a year. Regular oil.

My 2 vehicles only accumulate about 5,000 miles a year. So I do a yearly oil change on both. The 07 Jeep with 5.7 Hemi gets Mobil 1 5/20 and the 98 Jeep with the 4.0 gets Valvoline Max Life 5/30 (syn blend).
In the boat (4.3 V6) I recently switched to Quicksilver 25/50 syn blend; gets changed at the end of each season.
My yard equipment gets yearly changed or based on hrs. Mower straight 30 Delo, gen set Mobil 1 5/30, all the 2 strokes get syn blend 2 stroke oil (Echo Power Blend).

I can do it myself, but at this stage in my life I prefer to have the dealer do it for me. If they screw it up, it's their problem - both vehicles under factory warranties. They go in when the idiot lights pop up on the dash indicating an oil change is needed. Both get synthetic, or should, according to the owners manuals.

I will show my boys when they are of driving age how to do an oil change and tire rotation on their own so they at least have the info on how its down properly.

As for the boat...I rarely put on huge number of hours on the motor so it could, in theory, go 2 years. Yeah, yeah maintenance intervals and all. Generally have the marina change it as part of winterization.

The ecoboost F150 gets synthetic or synthetic blend every 3000 ish miles. The '69 F100 gets dino 2x/year, probably 1500 miles between each change.

Went back to 5/30 full synthetic extended interval Mobil 1 and a Wix filter on the F150 3.5 TT EB, 102K, here in TX we were at 45 days straight triple digits, after a day or two of 98, we are right back at it, I'll stay w/ synthetics, Mustang soon as the oil even starts to look dirty (3K on dino now) global warming now and Texas are brutal

I just wait for the Oil Monitor Light to come on, or if equipped, the Oil Life% to hit 0, with certain Caveats.
The car with the Change Oil Light was speced for Dino Oil, and it goes a long time. Since I have always used Syn, I go a few extra thousand before changing, it now has over 300,000 on it, and doesn't burn it, leaks a bit.
The Car with the % reading, would initially go about 10,000 between changes, but because the DI engine was creating abrasive Soot and was ruining the Timing Chains, GM reprogramed the Oil Life Monitor to shorter intervals. In cooler temps, a trip around the Block would drop the Life by 1%, so I ignored it and added a few extra thousand before changing it. At 9 yrs GM replaced the Chains under warranty. Drove the Car another 5 yrs before it was written off due to a Collision, and it didn't burn oil, at 200,000

Yeah, I just wait for the change oil message too in my f150. It does seem to go a long time between changes though, like about 12-13,000 km. I figure if that is calibrated for reg oil and I use synthetic, I should be good. However, there is one ford repair YT channel I like that says ford's service intervals are way too long, so IDK.

How about those of you who have diesels? Do you use synthetic? Would you during a new engine break in period - gas or diesel engine?
