Yikes! An expensive habit.

I'm taking some time for maintenance today. I just finished changing the motor oil in my D19, my 1965 12 yd dump truck and a 1984 Suburban. I had a spare filter for the tractor, but bought oil and filters for the other two. Just shy of $100! I still have another tractor and an F-250 with a 7.3L diesel engine (14 quarts!) to do next week. Normally I don't change all these vehicles' oil at the same time, so I guess I've got a little sticker shock going on.

Mine all seem to roll around at the same time. 6 qts for the Montana, 6 qts for the Ram, 14 qts of diesel oil and a fuel filter for the 7.3. I can burn a paycheck on routine maintenance.

Go buy you 14 quarts of Rotella T-6 Synthetic and a quart of Lucas to go in that 7.3... it'll cost you more than all the equipment you listed!! Only once a year on the synthetic... and it sure starts easier in winter!

Check your local O'Reilly's they have a special right now Mobile oil and a filter for $9.99 plus a $5 mail in rebate. I think the oil is a 10-40 or something like that. Used that on a friends Dodge the other day and yep it is one heck of a deal

What makes Synthetic Oil Better then normal Motor oil ????
it cost more, but I need to know how Synthetic is better /// I know the cost is better or more ...

I own a F150 ford with a v6 motor in it,I was told buy a friend that works for a ford garge to use exactly what the manufactor recomeneds 5-20 sen mobile one{I think},he claims if not the oil gallys will stop up,I also have a friend that works in a garge and he has had a lot of these motor come in with no oil pressure and timming chains rattling,The syn. oil is expensive but Im hoping for 300000 miles,it has 160000 on it now

Oil salesmen always trying to get me to go synthetic, and I'm sure it's a good product, But I just don't see the benefit. They show me the hammer grease for eight bucks a tube and tell me it's actually cheaper because I'll only be greasing 1/3 as much as I do now...meanwhile the dirt is still pouring in and not being removed by more frequent greasings it turns into lapping compound. Salesmen don't understand this. I don't understand salesmen. So I end up at J.W. Perkins for the 3.00/tube grease and 450.00/drum oil.

Flows when cold. Doesn't coke when hot and doesn't squeeze out from between the cam and lifters.

Like when you buy a new motor mower, "use only BP zoom"
Of course it won"t run on anything else.

Mobil one, I have found to be a very expensive oil,They have to pay for all that advertising emblazoned on racing cars. don"t you.

An oil salesman walked into my shop while I was assembling an engine. He looked down into the engine and said "I don't know the first thing about an engine". Then he went on to say "so and so big farmer bought two drums and so and so other farmer bought three drums. I knew who those farmers were and they traded tractors and combines so often they never had a chance to see how well his brand X oil worked. Jim

You can change it only once a year, but I will change mine more often. Your injectors use your motor oil to inject your fuel and when you pump dirty oil through your injectors you will be replacing them. BIG DOLLARS.

In regards to what ford recomends for the 4.6. It said in the manuals I had to use 5/20W Motorcraft Syn. blend or Motorcraft full synthetic or equivilant. I seriously don't think you will find a ford manual that recommends Mobil One syn. I have had 2 different F150 with 4.6, ran them over 200,000 with penz 5/20W regular oil. Never had a problem all. Synthetic definatly has advantages over regular oil. funtwohunt

For some applications synthetic is better. For other applications, it doesn't make much difference. Considering this is an old tractor site and there are thousands of tractors and equipment still running great that have never seen synthetic oil, it's hard to justify the benefits of the more expensive synthetic oil.

Regular oil changes and maintenance goes a lot further to extend the life of an engine than running synthetic oil for extended intervals. Also if you use synthetic and don't change it as often, other items like air filters can tend to get overlooked. A clogged air filter and/or sucking fine dirt will do more harm to an engine no matter what kind of oil you use.

Find out who hauls bulk oil into your local oil distributor. My friend has to be sure that all the oil is drained out of his tanker before he can reload. He sells Shell 15-40 for $10.00 per 5 gal. bucket. You have to bring your own bucket.

I'm a Ford technician and what is most important is the filter. Good 5W20 oil is important in the newer engines too but the problem is the cheap junk oil filters. The glue that they use in the filter gets into the oikl passages and plugs them up. TRASHES the engine. Only use Motorcraft filters if you drive a Ford!

There are only a couple of things that set Synthetic apart from regular oil. The most important on is that it will not break down do to heat until temps that would have long ago baked your Dino oil into a solid. The next is that it never thickens like regular oil in the cold. Synthetic will net you some power enhancment alibet minute. If drive properly perhaps 1/2 mpg increase or more.

I've always run Mobil One 20w-50 in the Roadglide since new, because of the temps the oil see's with an aircooled motor. The Silverado has had Pennzoil full synthetic 5w-30 every oil change but one. I put Mobil One Syn in and it absolutely didn't like it, milage tanked, and seals leaked. drained it and put back in Pennzoil and all was well.

Run Wally World 15w-40 in the wifes 300SD. It drips , and burns oil when I put in Rotella 15w-40. She runs it 5 miles each way to work so I change it every 6 months.

In a diesel pickup I'm not sure I would put in Syn unless the payback was from driving long distances regularly. With a llot of short drives and long idles, you should be doing the severe duty service interval and there is just no benefit to using Syn oil.

I will be buying a new to me Dodge Diesel 2500 with 83,000 miles and I'm still undecided what I will run in it.
