Is it alright to put synthetic oil in my van?

Some say synthetic oil is for high performance engines only, others say to get tuned up first, but most people say it is not a problem to make the jump. My van is a 93 Safari with 185K on her and she's due for an oil change. I recently tried slick 50 in my oil and she was not happy, but I'm just hoping to find some reassurance in trying something new with synthetic.Is it alright to put synthetic oil in my van?
I recommend it. but first motor flush all the old oil and sludge out. Use Amsoil crankcase cleaner or Seafoam. Mileage really means very little. Modern engines are made to such great tolerances because of emissions requirements, that wear is reduced. Slick 50 is a waste of money, because teflon only reacts with aluminum. And, it doesn't really do THAT very well. It can cause seal leaks. Regular oil ALWAYS makes sludge somewhere. Synthetic oils are just oils with longer hydrocarbon chains and higher doses of detergent. They handle heat and stress much better and the best of them produce NO sludge. Try Pennzoil Platinum after motor flushing with butyl cello-solve. It cleans while you drive. ONLY use it if the label states on it that it ';meets GM specifications.'; everyone gets fooled by the API service ratings. There is MORE to oil than that. Modern oils are car-maker specific. Royal Purple, e.g., has NO car-maker approval. Always, READ the label and match the spec's to your owner's manual fluid specifications. Use Mobil One, Amsoil, or ELF oil, but only if the label mentions GM on it somewhere. GET IT???Is it alright to put synthetic oil in my van?

With 185000 miles on the clock I don't think synthetic oil is the best choice. Synthetics work best in new engines from new where their high lubrication qualities are most appreciated in engines built to close tolerances. You should use a good quality multi-grade oil with sufficiently high viscosity to cling to engine parts over a wide temperature range. You should put an engine cleaner into the existing oil first and run it for a day or two. Drain out and fill with the multi-grade. Always fit a new oil filter and change the oil and filter more frequently than recommended, say every 10,000 miles. That will protect and care for your engine far better than just putting in a synthetic oil.
It's not recommended on vehicles with that many miles because the clearances in the bearings and stuff are a lot ehhhh looser? It may not provide adequate lubrication in those spots, but the rest of the engine would be ok. If you do, might want to use a thicker oil. In that situation I'd go with a synthetic blend.
The guys are right about high mileage vehicle. You will have leaks and will be wasting your money. If you really like the van, you may want to have it rebuilt and replace all the seals and bearings and use synthetic after the break in period.
dont need it really if you replace your oil right and when most car avble to go into the 400,000 range if right care is giving
My two cents:





I've been using regular oil for YEARS, and haven't had a problem.


With something that old with that many miles, why change now?
Wasting your money. Get a semi synthetic high mileage oil. It is not only better, but also will cut your consumption
with 185k put LUCAS in with your oil
