Should I switch to synthetic oil? 95 chev 225,000 miles

9 posts in this topic

My 95 chev silverado 1/2 ton with the 5.0 just hit 225,000 mi. This truck has been very good to me. It is in perfect running condition, and doesnt burn any oil. My question is should I switch to a synthetic oil, or at least a high millage conventional oil? Every thing seems to be running fine, may have lost a bit of power over the years.

with almost a quarter million miles why change?

You would expect me to say yes, but this time probably not.

My general answer has a catch word: you can use AMSOIL (or any other synthetic) in any sound engine. That is, that is not burning or using an excessive quantity of oil.

In the old series of small block GM V8s, most have a fair amount of valve guide wear that gum and varnish are holding together. AMSOIL will clean this out and reveal a potential problem.

To change, even to change brands or types of petroleum oil, may reveal a problem. In your case, keep doing what you have been and stay with the oil that got you to where you are.

I agree. You got that far with conventional oil, just stay with what you've been doing.

Few years back I bought a 1993 Corvette with 177k miles, Car ran fine for many miles, wife took it to work every day. I decided to take in at dealer for an oil change. I was 100% certain previous owner (cheap guy) changed oil with cheap stuff. Dealer replaced it with OEM synthetic. Car ran for approx 200 miles than developed a rod knock. Motor was toasted.

I just replaced oil in my new (to me) 1997 Dodge Ram 2500 Cummins diesel with 245,000 miles. I used Amsoil 15-40. Don't have a problem at all whatsoever, previous owner always used Rotella-T non synthetic.

I think I would follow everybody suggestion to stick with what you used so far, just to be on the safe side.

I had a 97 Mazda MPV- it had around 130,000 on it and I switched over to synthetic once. Had a lifter ticking bad after that, even after switching back to conventional, which I did almost right away. Bad mistake

    • The past week has had me having multiple close calls and missing a brute at 45 yards.  Tonight I talked my dad to give it another try and there were birds in the field when we got there.  Birds ended up leaving as we tried to sneak in.  A short 20 minutes later they were back and we watched and worked the big group of toms and hens for more than 2 hours before we got one to commit.  Dad shot him with his 20 gauge at 48 yards,(this thing shoots an awesome pattern).  The 3 year old was down and only flopped a few times.   Nice 1+ inch spurs, 10" beard and heavy.  A good evening for sure!
    • Sorry to disappoint guys, but this tom was not my first bird of the season. Apparently that's part of the rules. The score won't count towards the team. I don't have any measurements for the jake I shot so we will have a zero from me.    At least my freezer is full. 
    • Way to  go 1957 !! Congrats!!
    • sugar is not a drug. 
    • Another good day today out on Superior ,,,, Had my first double and triple in the new rig today ,,, the day didnt start out with perfect weather but the fishing more then made up for it ,,, The mud  covers a lot of water but fishing the tea  colored water and edges of the mud paid off ,,, the cohos grew 5 inches  from eating this years smelt,,,, had some go 23 inches today 
    • Say no to drugs, like sugar.  Yes, sugar is a drug.
    • I won't be able to post the scores for this week until maybe Wed. so if someone else wishes to do so feel free to do it. In fact for the entire summer season I'm going to be pretty much hit and miss. So don't count on me the lake is calling and I have no computer there. My scores will drop like a rock unless luck prevails.
