My car only has 400 miles on it right now. But I was wondering when I should switch to sythetic? Brand preferences? I saw that Mobil 1 now has a high mileage oil (15000 miles of gauranteed protection), but is there an oil filter that will last that long? Is there a special process to switch from regular to synthetic? Any info would be appreciated.

 

i used the fully synthetic oil not the blended. Also for the oil filter, it might be pricy for a filter but i would go to the dealer and buy the factory filter. Its about 7 bucks. And i also use mobil 1 full synthetic

 

I am running AMSoil 5W30 synthetic which they say is good for 25k miles. I am not and have not run the car more than about 5k miles without changing the oil. I am also running the Mobil one M1-105 oil filter. I think it was around $12 from Auto Zone. I am also looking into becoming an AMSoil dealer and may try to sell on here if anyone is interested.

mobil 1 goes thru my engine like beer.

 

i run 10w-40 high performance amsoil. The difference is very noticeable from the stock oil. Made a slight gain in mpg and the engine noise is less. But then again it could be just placebo, although the ecu doesnt lie, my mpg is up 2.0

 

i use quaker state.

and i only use 85 octane gasoline.

purrrrsss like a kitten.... meow.

 

85 octane?? I've never seen a gas station that sold that low of an octane.

 

Just curious, we use 5 quarts right?

 

i was just kidding... but i think the lowest they go is 85.. i may be wrong though.

 

I'm glad I'm not the only one who seems to use up mobil 1 for no good reason. Just gone! Not out the exhaust, not on the spark plugs, and its not on the floor. Majic

 

The Reason Its Drinking Oil Is The Synthetic Is Thinner Than Conventional Oil And Is Passing Through Places It Shouldnt. However Its Not Enough To Cause Problems. No Special Steps Have To Be Taken To Run Full Synthetic. Make Sure You Dont Have An Oil Leak Because It Will Make It Worse. Always Run The Factory Oil Filter. Us Dealers Can Decline A Warranty Claim On Engine Failures Due To The Incorect Filters. And Trust Me, Ive Seen Failures Due To Wrong Filters.

 

Way To Capitalize All Your Words. I Run Mobil 1 10W-30 in Socal. I Am Thinking Of Switching To Turbonetics Oil Soon. Saw The Analysis Brad Posted. Interesting Stuff.

 

That Is Quite An Interesting Post, I Must Say!

 

What analysis? can anyone post link?

 

I have run Mobil 1 since the 6000 mile mark. Have never had any oil burning issues whatsoever and I do changes every 3500 miles. Level stays the same.

 

you're lucky that your are not burning oil cuz everyone of my customers with a G35 were burning oil also and the factory reps said its normal with synthetic. i also drive the crap out of my car and drive 85 miles to work and dont change oil but every 6000 miles

SmO69 no offense, but o have had lots of customers get the wrong filter from auto parts stores. that is what i mean by being able not cover a repair. i have had many customers using the wrong filters, and that under law can void your warranty. trust me, most service advisors at the dealer want to cover a motor replacement because we get paid commision off the parts and labor. if i could put motors in all day long under warranty ill do it. how ever if i send a motor back with the incorrect filter the manufacturer will kick the claim.

 

Every car I've ever put Mobil 1 in slowly consumes it. I now run AMSOIL and have not had any oil consumption issues at all. All I hear on here is how people consume Mobil 1...I think it's Mobil 1 that is too thin...not synthetic in general. Since a vast majority of people that run synthetic run mobil 1 (probably beacause of it's availability), I would say that's where this theory is coming from.
