As long as you used the same viscosity/grade in both oils there would not be a problem as engines will run on both equally well. Have the noise checked out by an accredited mechanic before you go too far as it may be just coincidence

What happens when you use regular oil instead of synthetic oil in 2007 dodge ram v6


nothing
synthetic oil is good but it has the same problem as ordinary oil
the additives in the oil are all used up and no longer do what they are there for
neutralizing acidity from combustion
keeping moisture in suspension,retaining tensile strength in the oil film and a host of other additives used to promote longer engine life
regular oil is cheaper so more regular oil changes can be afforded( every 5000 miles )
forget the myth that oil doesn't have to be changed for 12 months or 20000 miles
oil is the most vital component in an engine so changing often is for longer engine life
as a point of interest , when you pull into a shop for a service the oil you will get is ordinary engine oil because if synthetic oil was used , you would scream at the bill and not go back there unless you specifically ask for synthetic oil
simple economics and business sense
more costly than anywhere else = no business

My cars oil light stays on the i just replaced the oil switch and oil pump the oil is not getting to the engine i stopped driveing it and it is at the shop what stopping it from getting oil to the engine


If you have a Chrysler 2.7 engines were made with oil passageways that are too small and get too hot. Unless you run only synthetic oil you have problems. The regular motor oil that most people use because it is cheaper slowly burns in the tiny passageways and builds up like cholesterol in a heart until the oil flows no more and the engine blows up. Chrysler did not want to pay to fix the problem, there fix was to recommend synthetic oil. Hope this helps.

What is the best type of engine oil for a lincoln LS


The best oil is the Synthetic type oil that one can get through Walmart or an auto parts store.
However, if the car hasn't been using synthetic type, it's a good idea to creep up on it using a mixture of synthetic and regular oil.

However, I have a couple of Cadillac Devilles that use regular oil and I've never had any problems with it.

I wouldn't use synthetic unless there is a sticker that specifically says to use it under the hood.

Most American cars don't need synthetic.

Some Porsches, BMW's, Mercedes Benz and higher end performance cars recommend synthetic for use all of the time.
Good luck on choosing the best grade of oil for your Lincoln LS.

Tapping noise on start up


Thats a good guess. Check your oil pressure if possible. You may need a new oil pump. The tapping could be pistons or valves when cold.
The oil light could be bad sender. They are not necessarily related. Don't replace anything until you determine the cause. ie: check oil pressure.

OIl, synthetic or regular, what's the difference?


Synthetic oil won't break down as quickly as conventional oil, gives better protection and longer life. Excellent product, I Strongly suggested for those out there who forget to do their oil changes regularly or courier/ work vehicles.
Heres the link to an explaination from Castrol
http://www.castrol.com/castrol/genericarticle.do?categoryId=8264018&contentId=6003233
I use conventional Oil in my jimmy with 5% of Lucas engine oil treatment and service the engine every 3,000 miles. I find it to costly for the Synthetic oil every 3,000 miles, and as for the high mileage oil you can buy. The high mileage oil has a higher fluid retention like adding Lucas engine oil treatment to any conventional oil, so you decide on what type of oil you like to use in your engine.
Good luck and hope this helps.

When the engine is started in a cold environment ( Canadian winter) there is a loud rattling noise. This noise disappears once the engine in warmed up. There is a corresponding high idle ( 1800 RPM) until...


it is probly your valve train starving for oil.I would try using a thinner oil in the winter time or just switch over to a full synthetic oil this should help.Once you switch to full synthetic oil though it is recomended to stay with it it is not good to go back and forth from synthetic to regular oil.
