Is synthetic oil recommended for a GM 6 cyl. with 130000 miles?

Yes it's safe just don't go more than 2000-3000 miles before your first oil change. The reason is that the synthetic really cleans out all the sludge (if your engine has it) and grime and will get filthy quickly. It's doing what it's designed to do. After that you can go to your recommeded oil change intervals.

Only if full synthetic was originally used.Otherwise, use Castrol part synthetic high mileage oil and a wix or purolator oil filter. The Castrol will last 5k miles before it needs changed. The Valvoline full synthetic is completely broken down by 3k miles. Off the shelf "full synthetic" oil is simply base oil with additional additives, it is junk. Schaeffer, Amsoil and Royal Purple make FAR superior products.

If you've been using synthetic for the life of the car I would say that is okay but if you are looking to switch from long-term conventional use the switch may cause leaks as synthetic seems to clean areas out more. I know this from working as an oil tech and seeing countless people come in and want to switch to synthetic and come back with new leaks that didn't exist before

No! Your 2005 Softail Deluxe calls for a 171-C. Also I would recommend Harley Davidsons Screamen' Eagle 20-50 Full Synthetic motor oil.

I've used it for over 7,000 miles in my FJR 1300 with a wet clutch. An excellent product, improved shifting,quieter and easier revving .I definitely recommend this oil.

Safest answer is to change whenever U change the oil..if the oil change interval is 5 k..and U do a great deal of hwy driving, U might stretch to every other oil change, but why, it's the cheapest expense..use synthetic oil and always change at least once per year

Yes its designed for small 4 stroke engine. Depending on your mileage, this or a standard oil/non synthetic oil will work.I only say depending on mileage because dealers and the manuals say not to use synthetic before 5000 miles, because synthetic oil is thinner than regular oil.So in short yes it will work if air temp. Is between 32 and 101f degrees f most of the year, and if your mileage on the engine is greater than 5,000miles. Change every 6k miles or 6 months, whichever comes first.

I too believe this lubricant was designed with Harley in mind. I use it in my 2006 Softail, I transition with 9800 miles / and I can see a major difference... Quieter, much smoother... And no clank! And actually better gas mileage. The other fluid I transition too is the "Mobil 1" synthetic 2 cycle V -twin motor oil ... This stuff is Great too !! / motor runs 15-20 degrees cooler + my gas is lasting longerIt's a bit pricey, but well worth it. I hope this response helps you out. Safe travels.

For my personal use and using Mobile synthetic oil,usually use it for up to 10,000 miles...

I would agree that it is since we have the same engine "technically". The issue you may want to consider is if you have been using a non-synthetic oil- this one is indeed synthetic and I hear that you shouldn't mix. If you are already using synthetic this is a fantastic oil for our cars.I am using it in a 2012 Audi A4 1.8T

You will want to purchase a high-quality 5W-30 or synthetic 0W-30, 4-cycle motor oil

That's more based on your car than the oil. I have a 2012 VW golf and the recommended interval is 10k miles.

You shouldn't run anything but synthetic in your turbo model. 5w-40 is perfect. exactly what the dealer uses. you will gunk up the engine if you use conventional oil.

What I've read and been told is that synthetic gear oil does not need friction modifier. I did not use any for my two jeeps. Visit their website for more clarification.

You can buy the XADO 1 Stage Maximum atomic metal conditioner and just do your normal oil changes. I use synthetic so I only change my oil every 10,000 miles.

Yes, I think so. The full synthetic racing oil will give you more lubrication and protection, especially at extremes. I noticed in my 2011 Kawasaki Concours which was already extremely smooth and quiet, that after I switched to 4T that it seemed to shift even smoother. I would recommend.
