I got some coupon for a $15 oil change with syn blend... I am on 5W30 (full syn)... can I use the blend for 1 cycle (probably go back to syn after)?

spanks in advance

gftgrill

yes you can go to a blend for 1 oil change. but I would probably just stick with the full synthetic.

^^ full synthetic ftw.

I wouldn't. $15 isn't worth toying with your engine.

Mobil 1 is all I run.

Motul in summer, Mobil 1 in winter.

okay... what about Mobil 1 extended performance?

it says it protects up to 15K miles... i'd probably do it till 10K..

is this safe?

How much more would it be to just replace it more often? And how does that cost compare to getting the engine rebuilt 50k or 100k miles sooner?

IIRC there's a thread (may be hard to find at this point, I can't seem to find anything before the forum update) where an engineer ran gas chromatograph or mass spec (can't remember which) on his oil after it had been run, and from this made some determination of engine wear - this may help answer your question. Regardless, it was a really interesting thread.

I use the Mobil 1 extended performance fully synthetic 5w30.. it also says good up to 15,000 miles but i change it every 3,000.. its alil over $7 a bottle though..

Maybe for an unaggressive driver. But if you're aggressive, it'll shorten the oil life. And do you really want your oil to sit in your engine for 10k with all that gunk in it? And if it's meant for longetivity, it probably means a sacrifice of performance.

The extended performance is probably for fleet cars, where people don't want to abuse the car because some fleet cars might have black boxes in them ;-P

Synthetic Blend should hold up fine. The owners manual even states conventional oil is good enough. It crazy how everyone in this thread thinks they're driving a Porsche. It's a Honda engine, nothing special...same one as the CRV!

my stupid coupon expired

Whoa P_S_ When I first read your post I thought "Mobil 1 and 3k changes, what a waste! like ordering a larger pizza and eating only one slice" But then I saw the fact that you had "times" along with your long list of mods and then thought well I doubt he is a mild driver.

But those who are just commuting and family driving could get away with many more miles than 3k with Mobil synth. That is the point of synth - longer intervals. Hey if you can afford the extra $$ for more changes and $$ oil that's cool.


My synth blend use was only once when I went to a nearby independent acura garage who uses synth blend by default (Castrol). I asked for full synth but he said that Acura engine gaskets were susceptible to leak with full synth. I just went with his recommendation. So in 30k miles, I have used full, blend synth and honda dino. hardly any difference to me in engine feel. maybe shifting is a little smoother for the first week of the oil change. I really don't have a stance. Dino seems fine for me. I save that money toward crazy $$ stereo cables at home where I can tell the difference.

$15 for a synthblend oil change? I'd be skeptical. I wonder if that even pays for the oil, let alone the filter, and the labor. Where was this?

Local AAA Automarks sometimes offer $20 oil changes, but that's their run o' the mill dino oil, cheap filter, no extras. I usually only pay $15-20 in labor plus the filter cost when I bring my own oil.

I believe I've read in other threads that Honda techs recommended dino oil for ... what? ... the first 10,000 miles to "set in" the seals and stuff, then switching to synth was ok? Memory is failing ... I'd check previous threads (heres a Google search for threads).[1]

I just use synth, get it cheap at Costco (last purchase was "buy 1 case, get a case free"). Changes on my engine seem to have been coming at around 5000-6000 miles (by the oil life indicator). I don't push it, I don't want a repair under my extended warranty to be declined with "you haven't done maintenance on time, so you're liable for damage."

[1] Guys, Google search seems to find old threads ... just preface your Google search with "site:tsx.acurazine.com."

Well, it's does have higher compression ratio resulting in the requirement for premium fuel.

Mobil 1 here. Change it roughly every 7-8K mi.

dom

I buy whatever full synthetic I find on sale. Its either Mobil, Castrol, Pennzoil or a local house Synthetic which is Shell oil.

Viking

Mobil1 every 5K

Fox137

Same here...

just changed mine yesterday at 92800 or so... next one is due at 100,000!

odannyboi

what kind? extended performance or just synthetic? I got mobil 1 5W30 right now and my service light says to service now (its been almost 5K with the mobil 1).

jlukja

Just synthetic. I buy a jug of it at Walmart and ask the dealer to use my oil when I take it in for the oil change.

Your car will not know the difference between regular and synthetic oil. The maintenance light will come on at the same point regardless of what kind oil you use.

dom

I'm sure the dealer mechanic is very pleased he's putting Mobil 1 into his car.



Do it yourself. I'm sure you know how easy it is. Except when its -20 outside. But you don't have those issues.

jlukja

Hush, you.

Stop agreeing with that little voice in the back of my head.

I'll have you know we're having a cool spell at the moment. It may not even make it to 80 today.
