Regular or synthetic oil Vegas 2016

Hi

This is probably a 50/50 question, my RV has 19000 mi. always used regular on my oil changes at 7,5000 mi./ea

My question is should I move to synthetic or stick to regular.

Open to any comments.

Thanks

I think you'll get some differing opinions here...
Personally I use 'regular' in RV... I change oil based on dates - not miles... and don't see enough benefit to be worth the extra expense.

Every Ford I own at the time (3) calls for 7500 but thatís w their synthetic blend oil. So not sure what is regular. I would not want to run any straight dino oil 7500 miles but thatís just my opinion. Dino oil breaks down w heat after a while and I wouldnít take that chance especially since lots of my miles are in the south.
GMC, just curious what dates do u use and what oil? Thx Dennis.

I do it annually... which for me is between 5000 - 6000 miles...
I have never hit the mileage limit in under a year - We stay in it a lot - but typically only a couple of longer trips in a year.
I typically do it in the fall - started when we were doing winter trips from MI to FL... so it was part of the trip prep.

If I was putting more miles on - and was changing based on miles - then synthetic would let me go longer and might be worth it.
But for my current usage - don't see a benefit outweighing the extra cost.

Last oil change Ford did - but when I do them (all but that one) typically use Castrol or Valvoline.

If you check around the only recommendation for extending oil change intervals by using synthetics comes from the synthetic oil makers.
What does your owners manual recommend for oil type & change intervals? That's what I'd go by.
If it calls for regular oil changed at 3000-5000 miles then, in my opinion, why spend 30-50% more for the synthetic. If your changing by time rather than miles then that would be a waste of money spending the extra for synthetic if it recommends regular oil.
Do you pump premium fuel instead of whatever the auto manufacturer recommends? Most likely not, due to cost. To me it's the same with the oil.

Just my .02 cents!!

Ford uses a synthetic blend and itís pretty cheap at Auto Zone and the like. No doubt itís fine. But exists to be cost effective. Personally, if Iím driving a $70,000 vehicle with a very hard working engine that also suffers from periods of non use Iím going to spring the extra $20 per year to use full synthetic. I prefer Amsoil but usually use Mobil 1 purchased on sale and I change my own oil so itís like $50 instead of $30 for Ford oil.

I agree completely. Why gamble with dino oil in a hard working motorhome engine. I cheaped out on an oil change in a 1985 air cooled sport bike once. The oil light would come on everytime I leaned into a fast corner. Never again!

Thanks to all, very helpfull info. Makes a lot of sense to use synthetic in my case, it sits for about 4 to 5 months in winter (Canada)
Travelling long distances in US starting March.
Regards

I use synthetic in all of my vehicles.You donít need to worry about the oil viscosity breaking down and I find that the vehicles run a bit smoother.Most new vehicles run on a synthetic blend or full synthetic these days.I wouldnít use anything but synthetic,it is worth the extra money in my opinion.

Yes, synthetic in all of my vehicles, including the 24.1 Axis. Life blood of the engine is worth the extra few dollars, same as a good quality oil filter vs. cheap ones.

I use Motorcraft 5W-20 blend and Motorcraft filter. I change every 3,500 miles.

My race motors use 20W-50 dino oil because of loose clearances.

I only use synthetic in cars that recommend it and never in race motors I build. Tried full synthetic in race motor once, looked like rings never sealed.
