Let's change from conventional oil to synthetic nothing but the best for my old 65, c-10, 6 cylinder. Now she smokes all the time. Tell me it is not too late to switch her back to conventional oil. I have been told yes I can and no I cannot. What I may have done that can or cannot be undone?
View 10 RepliesI have a 07 camry I4 with 56,900+ miles and it was using 10w30 conventional oil, but recently (2 weeks ago) I change it to 5w30 Mobil1 synthetic and today notice at start up white smoke, it didn't do this before with the conventional oil.
Is this normal with this type of change from conventional to synthetic or should I worry and try to go back to conventional and see if it stop.
Looking for changing transmission fluid to synthetic with next change. '05 Camry LE V6 with 100,000 miles. The fluid was changed last year by the previous owner, but as with many other new owners, I like to change out most/all fluids so I have a fresh start. Any issues with changing to a synthetic or is the Toyota fluid already synthetic/semi ? Also, would you consider 100,000 miles too high to change the engine oil to full synthetic ? Oil was changed by the dealer when purchased 2 weeks ago and still looks like new, but prefer using a full syn as with the wife's car, my Highlander, and my Harley.
View 14 RepliesOur Prius just passed 100K miles and I am no longer covered by any warranty on the ICE. I have been regularly changing oil every 5K using Castrol oil & Toyota filters but am planning to switch to Mobil 1 and changing interval to 10K. I change my own oil and we put lots of miles (30-35K/yr) mostly long distance traveling.
There have been some old wives tales about changing to synthetic oil on cars with a lot of miles. I assume that they are just that - old wives tales. I am fairly convinced by other posts here that going to 10K intervals is OK.
New diesel owner looking for some info? Currently approaching 9k miles. My first oil change was done by the dealer. I was looking at my owners manual on what weight of oil to use. I am thinking of going to a 5w-40 oil but all seems to be synthetic. Do i need to do anything special if i am going to change from a conventional to synthetic?
View 7 RepliesStarted having problems with my Chevy Malibu (1999, with 95,000 miles on it) while driving two times this week. Both times an alert warning flashed on my dashboard. The first time, flashed the brake check and ABS warning on the left side of the dashboard, and the second time the check oil and check battery warning on the right side. In both cases, after the warnings flashed, the car was still running, but stepping on the gas pedal resulted in no acceleration, but brakes still worked. The steering wheel also locks-up to the point where I can't turn any more. Both times, I stopped and shut off the engine, waited about 30 seconds and restarted, after which everything is fine and normal. The brake pads were changed recently, but not the rotors which may not be in very good shape.

View 14 RepliesSo ever since I picked up the truck from getting the springs swapped out the tranny has started to slip more and more. It's about at the point now where it does it at the 1-2 and 2-3 gear change every time unless I give it a little throttle so it shifts harder. It's just the normal shifting pause and then the slight jerk when the next gear starts. Time to a new torque converter, or am I looking at getting my whole thing rebuilt? If it's the converter I can give that a shot myself but if I have to have it rebuilt it's going to have to wait until January or February.

View 5 RepliesGot a 02 Jetta 1.8T 5spd auto tiptronic with 100k miles. Having issues with shifting. Trying to determine if its electronic or mechanical. Had a short in solenoid 10 N283 which melted the TCM. Put in a used N283 to see if the trans is still ok mechanically. Plan is if its ok to put new fluids and solenoid pack. What do the experts think does is need a full rebuild or will new electronics do the job?
After putting the used N283 solenoid the trans works but not correct. The problem is in the shifting only. Feels like its out of time. When you start moving from a stopped position from 1st to 2nd the car takes off good but when changing gears it reves and feels like its slipping then it hits hard into 2nd. Then 2nd-3rd is a fast shift and not hard. 3rd-4th slips and revs a little then changes gears 4th-5th is fine. all down shifts are fine. Does not mater if the car is hot or cold its the same.
If I disconnect the MAF 1st to 2nd shifts fine with no problems. 2nd-3rd little rough but not bad. Problem with disconnected MAF when going in Drive at 30-40mph all of a sudden it jumped into 1st gear and felt like I was slamming on the brakes.
With the MAF connected and I shift manually in tiptronic mode each gear runs real good with no slipping at all. But same problem happens when switching gears. I can drive it smooth if i accelerate to 3000 rpm and then left off the gas a little and it shifts fine.. Same with the other gears.
I got a used TCM to rule that out and the problem is close to the same. It tries to shift at lower rpm but still does about the same problem. I did recently had a MAF go out. Put in a new bosch and no change. Did my VCDS scan and only codes I get is "17840 secondary air". I can get operational data on some solenoids but not sure what parameters to look for.
Just did my first oil change on my 2015 Super Duty 6.2 engine. I got the Fram filter the book called for, a PH-2. There's goobs of room for the longer filter. Would that be the PH8A? The book is about to trying to figure the comparable long vs short filter. Why do they insist on those short filters when a full size will fit? My Dodge Ram Hemi was the same way.
View 14 RepliesActually a couple of questions. I've had one oil change in my F250 6.7. Getting close to the second one. So, my question is, what is the computer using to decide when to tell you that you should change the oil? And, if you changed to a synthetic oil, could you go longer between changes? And, if so, would the truck's sensors be able to tell the difference in the type of oil being used?
View 4 RepliesThe tire pressure monitor comes on when there is only .5 difference in one tire. Then it won't go off.
Also, the driver's side mirror will not program and it has a mind of its own just changing randomly every time I back in.
Bought a 2009 Chevy HHR with 35,000 miles in July, 2010. In the summer of 2011 the ignition was replaced, as the key would not turn. (The engine was running at the time. It was necessary to disconnect the battery to turn off the engine.) At 55,000 miles the transmission suffered "catastrophic failure" and the entire transmission assembly was replaced. (The engine light never came on, although the transmission was slipping frequently.) After driving the car with the new transmission between 100 and 200 miles, the engine light came on. The error code indicated a faulty transmission fluid pressure switch. The transmission changed gears harshly at times and the automatic door locks stopped working properly. Sometimes they would lock when the car was taken out of "park" and sometimes not. Likewise, they would not always unlock when the transmission was put in "park." After replacing the switch, the technician said that for no reason the security light came on briefly as did the passenger airbag "on" indicator light. Once again, after having driven between 100 and 200 miles, the engine light is on again, and gears are sometimes changing harshly. No diagnosis yet. Do I need an exorcist?
View 7 RepliesI need to replace the safety switch on my 1995 S10 w/ a 5 speed manual tranny. It doesn't seem to want to come out. Looking at the new one, I would guess that it MAYBE fits in sort of like the holes on a wall hanger. You know, sort of a pear shaped hole that a screw or something fits into and slides down to make it stay. Am I right? And if so, how hard is it to get out/replace? I don't really want to destroy the old one, but that is looking more and more like how it's going to happen.

View 2 RepliesMy truck was noticeably sluggish when it shifted into overdrive or would refuse to shift into it all together, so I decided to change the filter and fluid in it. After this maintenance task was done, and I test drove it, I noticed the problem was still there. It also seems now that it has trouble shifting in all gears. When I tried to "manually" shift it through all gears, the transmission would hold it in the previous gear, buck, shake and then shift at a higher RPM.
Not only this, but if I floor the pedal, the truck doesn't want to drop to a lower gear to increase RPM. It only bucks and carries on until I let out of the gas. I also noticed that when I rev the engine in park, the engine does not want to go past 4,000 RPM, and I hear a "grinding" noise at about that range. In the past, I could red-line the engine in park/idle no problem. Does the auto trans have the ability to "hold back" the engine or do I have deeper engine problems?
I am trying to change spark plugs and wires on my 2001 Impala with a 3.8 liter. I was able to get the boots off of the front plugs OK but I am having trouble getting a good grip on the rear ones. It seems like they have glued themselves to the plugs. Removing the boots?
View 10 RepliesFor the last couple of years, I've noticed the air flow changes from the floor to the defroster under hard acceleration. Not a big deal. This morning (7 degrees) the airflow was changing under light to moderate acceleration. It's a vacuum problem, but is there anything in particular I should be looking at? The car is running fine, no issues with stalling or hesitation.
