Has anyone made the switch to synthetic oil? If so did you notice a change in performance? How long have you gone between oil changes? I am coming up to my first oil change since I have owned the car, so I want to know if it is worth it, I would be changing the oil myself in the future.

Honestly for me I have not seen any difference. I change every 5K miles. I use regular in my Explorer, & synthetic in the CL.

I mostly use M1 sythetic.. I notice a *slight* difference but use it more for change intervals and stability.

I think the key is to use a good oil filter. The Purolator "extra super special" (or whatever it's called) is a good choice.

Tons of people here use synthetic. I use Mobile 1 oil and filter. Haven't noticed much of a difference, but I use it for the change intervals.

I have a 2001 CLS and I changed from regular to synthetic. The main reason is you can wait 7,500 to 12,000 miles between oil changes. Plus, if you do it yourself, it cost the same as having Penzoil put regular in your car. Synthetic is for extreme weather conditions and for driving very fast. Basically, it comes down to length you can go without changing your oil and it makes me feel better inside.

You want to commit to that statement. Driving fast puts no additional stress on your engine. Its the high RPMs and cold starts that stress the engine.

Well, I live in Boston, so for months I have cold starts, my boyfriend uses Mobil 1 in his maxima and still changes it every 3,000 miles, but he is psychotic. I think I just want the peace of mind knowing that I can have that extra mileage cushion.

phipark

I good reason to switch over then.

If you are going 125 mph down the highway everyday, then you'll be in 5th gear and running at a high RPM. Thus you will be driving fast.

- you just got hit with the big nuts

Wow thats one of the most intelligent posts ive ever seen

You just proved my point when you said high RPM. Its not the fact that your doing 125 that stresses the engine is the higher RPM. Trust me if your cruising down the road at 35mph, but your holding your engine at 6500 RPM then its much worse than doing 100 MPH at 3K RPM. When you learn something come back and post

those that use syntheetic, does anyone use a 0 weight oil?

ChucksCL-S

How about 199,000 miles on my (now in my brother's hands) old '00 TL, all on Mobil 1 or Amsoil changed every 8K. Car still runs perfectly and has yet to need ANY oil between changes...doesn't burn or drip any, nothing. And this engine saw plenty of right foot abuse too!

Sun Diego CL-S

Right foot abuse good. AND bad.

I actually thought my car performed worse on synthetic, and it was a bit shaky at idle. But the place i got the oil change at was a bit shady, never going there again.

GreenMonster

I used to run mobil 1 in my 94 tbird (v8), but that was mostly because I wanted to extend the oil change interval. I drove almost 130 miles each work day (60 something one way)....

I've been doing the dino thing with the CLS...

NiteQwill

Syn (Mobil 1 & Wix Filter) on the all my cars. Change at 7500 on my CLS, 10K on the VW. All oil analysis' every year turn up good, no excess metals, deposits, etc.

btw...

I'm surprised nobody has started with the AMSOIL HOLY WAR.

My reason that I am using synthetic oil only is because I don't have time to waste going to a mechanic. I change my oil every 6000-7000 miles and rotate tires at the same time(very convinient). If you have time to change oil every 3K miles, regular oil should be OK. I know that manual says that 7500 is OK for regular oil as well, but it assumes perfect driving conditions (highway only). Since I drive 50/50, and offten stuck in traffic, I'd prefer a peace of mind and thats why I use synthetic oil.

I use M1 synthetic only with either a Fram or Honda filter. I have a friend who works for Penske Racing. He does a lot of work around the indy cars and he told me this little fact. Penske in their indy cars use only M1 15W-50 synthetic. He also told me that during the summer months you SHOULD only use 15W-50 synthetic because its hotter out and this oil lubricates better since its thicker. While in the winter you should use what the car says to use being 5W-30 i think. I asked him about the oil pump wearing out faster and he says that its not a problem because although the oil might be thick, it just doesnt wear the pump out.

I was in Advanced Auto Parts the other day and they had a video playin on their TV's talking about Synthetic compared to Regular. They said that the synthetic oil is better because it just is! Lol. They really didnt go into details other than the fact that you can change it less often and that its better for the engine.

I might also add, that this guy has an 04 Subi STI and he redid his entire suspension on his own in the shop. Meaning that EVERY suspension component was taken out, modified upon, thrown away, new parts designed, made, and installed... He says that it handles like its on rails taking 90 degree turns at 50 is not a problem at all. Then he took me for a ride in it. I was at a lose of words... The car held every corner without a squeel from the tires.

The winter months are taxing to an engine upon cold starts....dino oil seems to lend itself to
longer turn-over time - putting that much burden on starter motor and battery. Synthetics have been better in that respect, and possibly reduce friction in higher revving engines...mileage, anyone?

NiteQwill

Fram makes Honda filters. Fram filters SUCK Paper element, piss-poor aluminum casing, etc.

15W-50 is way too thick for our cars. That weight oil is used in track motorcycles, track cars, and production super cars (Corvette for example). Plus, fuel economy would suck running such a thick oil.

Oil is based on environmental factors the vehicle is placed in. 5W-30 has the same protection factors as 15W-50 in corresponding climates, the differences are little or none.

I never listen to friends when in regards to maintenance... do your own research and anaylsis and you can come to your own conclusions.

NiteQwill

The whole purpose of synthetics is the friction modifiers that are added in SAE SL/SJ type engine oils. They reduce friction and increase protection via long cheimcal chains.

Now, OTOH, there are synthetics that do not have added friction modifiers, yet are still synthetic because of their refined/manufactured status. Example is Shell's Rotella Syn MultiGrade. Mainly used in environments where there is a great deal of interaction of moving parts (ie. wet clutches, slippers, etc.) that require a great amount of friction to move, but need the protection of synthetics

Fram filters aren't the best filter anymore. Tests have proven otherwise. Read here. These guys say Purolator is the best for the buck. Also, consider the source when receiving advice from a pro racing shop. While most of us change our oil every three thousand miles, these guys replace the entire ENGINE every five hundred miles, and they never go anywhere! These guys never drive their cars in the rain or snow, nor when it's really cold outside, they don't have traffic lights to deal with, and they know that their gasoline is always top notch.

I recently had dinner with an athlete friend of mine after he had run a marathon. While I was full after a small steak and some fries, he gobbled a huge order of mozarella sticks, two orders of spaghetti, five dinner rolls, huge salad and dessert. While I weigh over 200, he weighs less than 150. While I sit around on my fat ass and surf the web, he's outside running around like an idiot, training for the next race. His and my needs for food are quite different, as are the differences between a race car and a street car. Food for thought.
